Python Tutorial: Slicing Lists and Strings
 
10:44
In this video we will look at how to slice lists and strings in Python. Slicing allows us to extract certain elements from these lists and strings. This can be extremely useful for stripping out certain values from lists or getting a substring of a characters from a string. Let's take a look at a few code examples.

Indexing list in Python is a very important concept which gives us the ability to access our objects that appear in a list. List in Python can contain a lot of information that is important in order to run our programs and having a way to access the content within a list allows us to use the content as it is needed when our program runs. Indexing allows us to access one object and slicing allows us to access numerous objects at one time. Indexing List In Python Explained [table id=9 /] In the above table, you can see the indexing of a list is very similar to indexing strings. The only difference is that in the list each object holds an index position where in strings each character holds an index position. As always the index always starts at 0 and counts up for each object contained in a list. If we want to access an object going from the end of a list(right to left), we use a negative index number. The last index position when going right to left always starts at -1. Examples Of Indexing List in Python Access Index From Left To Right a = ['List', 12345, [123, 456]] a[1] 12345 a = ['List', 12345, [123, 456]] - We create a list object that contains a string object, number object and another list object. We assign our list object a variable named 'a' to represent the list. a[1] - We call our list object via the variable 'a' then we request the index position of 1. 12345 - We are returned the 1 index positions object which happens to 12345. Access Index From Right To Left a = ['List', 12345, [123, 456]] a[-1] [123, 456] a = ['List', 12345, [123, 456]] - We create a list object and assign the list a variable of 'a'. a[-1] - We then call our list via the variable of 'a' and we then index from the right using a negative index position. Remember when indexing from the right we need to use negative numbers and the starting index position from the right is -1. [123, 456] - We are returned a list that was contained in our list object. The list object is the last object contained in the list and we used -1 to access this list object. Conclusion In this Python tutorial, we looked at accessing list using indexing which is vital in programming when using list. If we can not access our content stored in list then list would be useless. We can pull one object out of a list using indexing if we need to pull more we could index multiple times or we can use slicing which we will cover in the next tutorial.

Iterate means looping through a procedure in programming. We will figure out how experience a list and print every item contained in a list in Python. We will utilize a for loop in Python. We quickly took a gander at for loops in the string segment of our instructional exercises. The for loop will experience every article that shows up in a list and print that question or give back that protest one time. On the off chance that we have to give back every item contained in a list of the for loop is our best alternative. We could likewise fulfill this errand by indexing every article, except that would take forever and take a great deal of code. Our objective when programing is to restrain the measure of code composed to perform an assignment. For Loop Syntax for variable in arrangement: print(variable) For Loop Syntax Explained for - Indicates to Python that we need to iterate through or loop through our sequence(list, dictionary(keys), tuples, strings, and so on.) variable - This variable can be anything that meets the Python variable rules. I think about this variable as only a placeholder for every item contained in a list. in - In is an administrator in Python that check for the enrollment. I think about this as is it in that list, word reference, tuple, string, and so on. This implies is it a player in that question. : - Colon demonstrates the begin of a piece of code. We will see a considerable measure of colons later on instructional exercises print() - Print is still some portion of the for loop which is alluded to as a square of code. The print articulation will print every item contained in the arrangement to us. variable - This is the same variable in the for loop line this equitable calls the placeholder variable so Python knows which questions print. Cases Of Iterating in Python Using The For Loop a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] for var in a: ... print(var) ... 1 2 3 4 5 6 7 8 9 10 a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] - We make a list protest that contains the numbers 1 through 10. We allocate the variable of "a" to speak to the list object. for var in a: - We then perform a for loop on our list object. In the first place we incorporate the for which demonstrates we need to iterate through the list object. We then appoint every article contained in the list question a provisional variable which we allude to as var in this case. At that point we utilize the in administrator to advise our project to look in the list item speak to by the variable 'a'. print(var) - Important we have to include two spaces before this line of code. We incorporate our print explanation to show we might want to print every item that is spoken to by the transitory variable of var. Given back our articles - We are given back every one of items contained in our list object. Notice every one is imprinted on another line. Essential Infomation About The For Loop The principal line must have a colon( : ) toward the end. The second line must be indented( two spaces) We can utilize else discretionary statement in a for loop. The interim variable can be anything you need the length of it meets Pythons variable rules. Conclusion In this Python instructional exercise, we figure out how to iterate through a list utilizing the Python for loop. On the off chance that you have any inquiries concerning iterating please leave a remark beneath.

Arrays in Python: Two Sum Problem
 
14:05
In this video, we are going to be solving the so-called "Two-Sum Problem": Problem: Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. We investigate three different approaches to solving this problem. Method 1: A brute-force approach that takes O(n^2) time to solve with O(1) space. We loop through the array and create all possible pairings of elements. Method 2: A slightly better approach time-wise, taking O(n) time, but worse from a space standpoint, with a space complexity of O(n). In this approach, we make use of an auxiliary hash table to keep track of whether it's possible to construct the target based on the elements we've processed thus far in the array. Method 3: This approach has a time complexity of O(n) and a constant space complexity, O(1). Here, we have two indices that we keep track of, one at the front and one at the back. We move either the left or right indices based on whether the sum of the elements at these indices is either greater or lesser than the target element. The software written in this video is available at: https://github.com/vprusso/youtube_tutorials/blob/master/data_structures/arrays/two_sum.py Do you like the development environment I'm using in this video?

First off we are never changing the original tuple instead we are actually creating a new Python tuple. With that being said we are not saving our newly created tuple either so we have to assign a variable to represent the tuple. We repeat the data in a Python tuple by using the asterisks or the multiplication operator. This will allow us to repeat the data in the tuple. This is similar to how we repeated strings and list. If you have any questions about repeating data in a Tuple leave a comment below and we will help you out.

How To Slice A List In Python 3

Be sure to like, share and comment to show your support for our tutorials. ======================================= Channel - https://goo.gl/pnKLqE Playlist For This Tutorial - https://goo.gl/EyZFti Latest Video - https://goo.gl/atWRkF Facebook - https://www.facebook.com/mastercodeonline/ Twitter - https://twitter.com/mastercodeonlin?lang=en Website - http://mastercode.online ====================================== Slicing List In Python In this Python instructional exercise, we figure out how to utilize slicing list in Python to get to numerous articles in an arrangement which are contained in a list. We can get to various items in a list utilizing file, however we would need to accomplish more work to do this so we can swing to slicing to snatch protests that are in a request. Slicing list is like slicing strings. Slicing List Syntax [LIST][Start : Stop : Step] [LIST] - This our list object which we will slice. Begin - This is the place our slice will begin. We utilize the list area to begin the slice of articles. Stop - This is the place our slice will stop. We utilize the list area to stop the slice of articles. The record position utilized as a part of the stop file really shows the ceasing point which is one item after the genuine halting point. Step - Step shows if the slice will skirt objects in a succession. For instance, in the event that we showed 2 here then Python would skirt each other article. Illustrations Of Slicing List In Python Illustration 1 a = ['String', 12345, 'StR'] a[:] ['String', 12345, 'StR'] a = ['String', 12345, 'StR'] - We make a list question that contains two strings and one set numbers. We utilize the variable "a" to speak to the list object. a[:] - We call the list objects by means of the variable 'a'. We then perform a slice from the begin of the list to the end of the list objects. On the off chance that we do exclude a beginning list than the beginning record will default to the 0 file position. On the off chance that we don't give a completion record position then the closure list position will default to len(a) which will give back the quantity of articles contained in the list object. ['String', 12345, 'StR'] - We are given back the full list since we sliced from the earliest starting point to the end of the list. Case 2 a = ['String', 12345, 'StR'] a[1:] [12345, 'StR'] a = ['String', 12345, 'StR'] - We make a list protest that contains three items. We utilize the "a" variable to speak to our list object. a[1:] - We call our list object by means of the variable 'a'. We then slice from the 1 list position to the end of the string. [12345, 'StR'] - We are given back a list that contains two items. We are given back a list beginning at the 1 list position since we advised the slice to begin at the 1 file position. Sample 3 a = ['String', 12345, 'StR'] a[0:2] ['String', 12345] a = ['String', 12345, 'StR'] - We make a list question that contains three protests and appoint the variable "a" to speak to our list object. a[0:2] - We call the list object by means of the variable "an" and we slice from 0 record position to the number 2 file position. Keep in mind when utilizing the ceasing record position the position before our stop position will be shown. ['String', 12345] - We are given back a list question that contains the initial two items in our list. Sample 4 a = [1, 2, 3, 4, 5] a[0:6:2] [1, 3, 5] a = [1, 2, 3, 4, 5] - We make another list question that contains a few numbers and is spoken to by the variable 'a'. a[0:6:2] - We call the list object through the variable "an" and after that we begin our slice at the 0 list position and end our slice at the 6 record position. The third contention is venturing and we are customizing Python to give back each other number to us. [1, 3, 5] - We are given back another list protest that avoids each other number to return us 1, 3, 5 Conclusion In this Python instructional exercise, we take a gander at slicing list in Python. On the off chance that you have any inquiries concerning slicing list please leave a remark underneath. Python 3.5.0 utilized as a part of this instructional exercise.

Our goal is to help each other reach our dreams through friendship and cooperation. As you can see below, a bunch of us have joined forces to make this happen: authors, editors, subject matter experts, app reviewers, and most importantly our amazing readers! --- Swift Tuples: (https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/TheBasics.html) Swift is a new programming language for iOS, macOS, watchOS, and tvOS app development. Nonetheless, many parts of Swift will be familiar from your experience of developing in C and Objective-C. Swift provides its own versions of all fundamental C and Objective-C types, including Int for integers, Double and Float for floating-point values, Bool for Boolean values, and String for textual data. Swift also provides powerful versions of the three primary collection types, Array, Set, and Dictionary, as described in Collection Types. Like C, Swift uses variables to store and refer to values by an identifying name. Swift also makes extensive use of variables whose values can’t be changed. These are known as constants, and are much more powerful than constants in C. Constants are used throughout Swift to make code safer and clearer in intent when you work with values that don’t need to change. In addition to familiar types, Swift introduces advanced types not found in Objective-C, such as tuples. Tuples enable you to create and pass around groupings of values. You can use a tuple to return multiple values from a function as a single compound value. Swift also introduces optional types, which handle the absence of a value. Optionals say either “there is a value, and it equals x” or “there isn’t a value at all”. Using optionals is similar to using nil with pointers in Objective-C, but they work for any type, not just classes. Not only are optionals safer and more expressive than nil pointers in Objective-C, they’re at the heart of many of Swift’s most powerful features. Tuples group multiple values into a single compound value. The values within a tuple can be of any type and don’t have to be of the same type as each other. In this example, (404, "Not Found") is a tuple that describes an HTTP status code. An HTTP status code is a special value returned by a web server whenever you request a web page. A status code of 404 Not Found is returned if you request a webpage that doesn’t exist. let http404Error = (404, "Not Found") // http404Error is of type (Int, String), and equals (404, "Not Found") The (404, "Not Found") tuple groups together an Int and a String to give the HTTP status code two separate values: a number and a human-readable description. It can be described as “a tuple of type (Int, String)”. You can create tuples from any permutation of types, and they can contain as many different types as you like. There’s nothing stopping you from having a tuple of type (Int, Int, Int), or (String, Bool), or indeed any other permutation you require. You can decompose a tuple’s contents into separate constants or variables, which you then access as usual: let (statusCode, statusMessage) = http404Error print("The status code is \(statusCode)") // Prints "The status code is 404" print("The status message is \(statusMessage)") // Prints "The status message is Not Found" If you only need some of the tuple’s values, ignore parts of the tuple with an underscore (_) when you decompose the tuple: let (justTheStatusCode, _) = http404Error print("The status code is \(justTheStatusCode)") // Prints "The status code is 404" Alternatively, access the individual element values in a tuple using index numbers starting at zero: print("The status code is \(http404Error.0)") // Prints "The status code is 404" print("The status message is \(http404Error.1)") // Prints "The status message is Not Found" Tuples are particularly useful as the return values of functions. A function that tries to retrieve a web page might return the (Int, String) tuple type to describe the success or failure of the page retrieval. By returning a tuple with two distinct values, each of a different type, the function provides more useful information about its outcome than if it could only return a single value of a single type.

What Is A Dictionary In Programming?
 
00:47
A dictionary in Python is a collection of unordered values accessed by key rather than by index. The keys have to be hashable: integers, floating point numbers, strings, tuples, and frozensets are hashable, while lists, dictionaries, and sets other than frozensets are not. Let's compare what can dicts do here are some other sites that have surveys or dictionaries of programming languages. Dictionary {} dictionary['cat'] 'frisky' 1 sep 2010 dictionaries manage pairs of keys and values. We will explain in more details what hashing and hash tables mean why they are such an important part of programming.

In prior lessons, we reviewed how to access elements of a list through their index location and even change their value. Methods addressed in part 1 add new functionality, such as adding new elements to a list (as opposed to changing values that already exist), removing items from a list, returning items from a list, and reversing the order of the list. Methods addressed in part 2 add functionality such as alphabetizing and sorting a list, inserting items to the middle of the list, and even randomizing objects in a list. This is an introductory series of Python tutorials. This course, from start to finish, is designed to help someone who has never programmed before learn the basics of coding in Python. As this series continues, we examine more advanced Python techniques, functions, and methods. You can download a copy of Python from http://www.python.org/downloads/. Keep in mind this tutorial is using an older version of Python, v3.2.5. You will need to click on the "View Older Releases" button to use this specific version. Using the newer versions will not be an issue at this point, but when the lesson proceeds to basic graphics, the Pygame Module we'll use does not support v3.3+ at this time.

Python Tutorial v3.2.5 Lesson 23.1 - List Data Type Introduction (1 of 2)
 
14:05
1:38 Skip the introduction to Lesson 23.1 5:01 Skip to the use of the min(), max(), and sum() functions. 7:19 Skip to using index notation to access list elements. There is no Challenge Program for Lesson 23.1 Lesson 23.1 introduces the List data type. Lists are created by using brackets [] and separating items in the list with a comma. Each item in a list is referred to as an element of the list. These elements can by integers, floats, strings, or any other data type. In addition, lists can hold multiple data types at ones (such as number and strings together). Lists are among the most useful of all the data types and all advanced programs will use lists. This lesson focuses mainly on demonstrating list properties through the Python shell. Future videos will focus more on the application of lists rather than singular properties. Due to the length of this video, it has been separated into 2 parts. This is an introductory series of Python tutorials. This course, from start to finish, is designed to help someone who has never programmed before learn the basics of coding in Python. As this series continues, we examine more advanced Python techniques, functions, and methods. You can download a copy of Python from http://www.python.org/downloads/.

Python Programming Language | Data Types | Booleans, Lists Commands in Python | Lecture 3 |Continued
 
11:33
Python Programming Language: Computer Applications Python Programming Language | Data Types | Booleans, Lists Commands in Python | Lecture 3 | Continued Review: In the previous video, we had seen Python Coding: • Launching of Anaconda navigator • Jupyter notebook used for the presentation Primary Data Types • Integers • Decimal Number - floats • Strings In the current video we will see two more data types: • Booleans • Lists Open Jupyter Qt Console, it is one of the products which come along with Anaconda. Boolean:- • Boolean variable is a statement that can be either true or false. • Boolean variables are usually used for comparison • The comparison symbols used are as follows: o Less than o Less than & Equal o Greater than o Greater than & Equal o Equal to o Not Equal to • These will become very handy when we use IF statement, and the For Loops • Logical Arguments “And”, “Or” and “Not” are also introduced here. Illustration of these commands in the programs: Lists:- • A list is a sequence of objects; they do not necessarily have to be numbers Illustration of List in a program Illustration of 2 lists in a program and concatenation of two lists Range command:- • One way to create a list in Python is using the Range command, which is very common in Python. • Illustration of different ways of using the Range command to create List Slicing:- • Slicing works with List as it works with string, which we saw in the previous video – limiting the list to a certain value Illustration of slicing • We can change the elements in a list using this • Multiple elements can be changed simultaneously • We can also check if an element is present in the list • This will be helpful when we use IF Statement and For Loop • We can have list of Lists Methods that go with the list:- d.append d.count d.extend d.index d.insert d.pop d.remove d.reverse d.sort .

Python Tutorial for Beginners 8 - Python Slices or Slicing
 
11:35
In this video I am going to show How to use Slice function or slicing with Python Collections. Also I am going to show how to use Negative index with Python Collections. So What is Python Slice? A slize is a span of items that are taken from a sequence List slicing format: list[start : end: step]. Span is a list containing copies of elements from start up to, but not including, end If start not specified, 0 is used for start index. If end not specified, len(list) is used for end index. Slicing expressions can include a step value and negative indexes relative to end of list. And What is Negative Indexing In Python: I a Python Collection such as Lists, Strings, Tuples, Bytes .. we can refer to an element by a negative index representing how far it is from the end. example # +---+---+---+---+---+---+ # | P | y | t | h | o | n | # +---+---+---+---+---+---+ # 0 1 2 3 4 5 ---- Positive Index # -6 -5 -4 -3 -2 -1 ---- Negative Index -------------------Online Courses to learn---------------------------- Blockchain Course - http://bit.ly/2Mmzcv0 Big Data Hadoop Course - http://bit.ly/2MV97PL Java - https://bit.ly/2H6wqXk C++ - https://bit.ly/2q8VWl1 AngularJS - https://bit.ly/2qebsLu Python - https://bit.ly/2Eq0VSt C- https://bit.ly/2HfZ6L8 Android - https://bit.ly/2qaRSAS Linux - https://bit.ly/2IwOuqz AWS Certified Solutions Architect - https://bit.ly/2JrGoAF Modern React with Redux - https://bit.ly/2H6wDtA MySQL - https://bit.ly/2qcF63Z ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL -------------------------Stuff I use to make videos ------------------- Stuff I use to make videos Windows notebook – http://amzn.to/2zcXPyF Apple MacBook Pro – http://amzn.to/2BTJBZ7 Ubuntu notebook - https://amzn.to/2GE4giY Desktop - http://amzn.to/2zct252 Microphone – http://amzn.to/2zcYbW1 notebook mouse – http://amzn.to/2BVs4Q3 ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter - Python Slices python tutorial for beginners pdf python tutorial for beginners with examples best python tutorial for beginners python tutorial for beginners ppt python tutorial for beginners video basic python tutorial for beginners learn python tutorial Verwandte Suchanfragen zu python slices python string multiple lines python slice list python string slice python länge einer liste python multiple assignment python string to tuple python string abschneiden python compare tuples

Sorting is a fundamental task in software engineering. In Python, there are a variety of ways to sort lists, tuples, and other objects. Today we talk about the sort() method which is an in-place algorithm for sorting lists. We also cover the sorted() function which can be used on more objects, and creates a sorted copy, leaving the original object unchanged.

Python Tutorial for Beginners 2: Strings - Working with Textual Data
 
21:12
In this Python Beginner Tutorial, we will begin learning about the string data type. Strings allow us to work with textual data in Python. We will be going over different ways to format strings, and also a lot of useful string methods. Let's get started. The code from this video can be found at: https://github.com/CoreyMSchafer/code_snippets/tree/master/Python-Strings Watch the full Python Beginner Series here: https://www.youtube.com/playlist?list=PL-osiE80TeTskrapNbzXhwoFUiLCjGgY7 Slicing Video: https://youtu.be/ajrtAuDg3yw String Formatting Video: https://youtu.be/vTX3IwquFkc If you enjoy these videos and would like to support my channel, I would greatly appreciate any assistance through my Patreon account: https://www.patreon.com/coreyms Or a one-time contribution through PayPal: https://goo.gl/649HFY If you would like to see additional ways in which you can support the channel, you can check out my support page: http://coreyms.com/support/ Equipment I use and books I recommend: https://www.amazon.com/shop/coreyschafer You can find me on: My website - http://coreyms.com/ Facebook - https://www.facebook.com/CoreyMSchafer Twitter - https://twitter.com/CoreyMSchafer Google Plus - https://plus.google.com/+CoreySchafer44/posts Instagram - https://www.instagram.com/coreymschafer/ #Python

C PROGRAMMING A MODERN APPROACH TUTORIAL 7
 
12:48
THIS C TUTORIAL COVERS ARRAYS IN C INCLUDING BOTH SINGLE DIMENSIONAL ARRAY AND MULTIDIMENSIONAL ARRAY. C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems. C was originally developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs, and used to re-implement the Unix operating system.It has since become one of the most widely used programming languages of all time, with C compilers from various vendors available for the majority of existing computer architectures and operating systems. C has been standardized by the American National Standards Institute (ANSI) since 1989 (see ANSI C) and subsequently by the International Organization for Standardization (ISO). Many later languages have borrowed directly or indirectly from C, including C++, D, Go, Rust, Java, JavaScript, Limbo, LPC, C#, Objective-C, Perl, PHP, Python, Verilog (hardware description language) and Unix's C shell. These languages have drawn many of their control structures and other basic features from C, usually with overall syntactical similarity to C that sometimes includes identical simple control structures. C is also used as an intermediate language for other languages, and for building standard libraries and runtime systems for higher-level languages, such as CPython. In computer science, an array data structure or simply an array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored so that the position of each element can be computed from its index tuple by a mathematical formula.The simplest type of data structure is a linear array, also called one-dimensional array. For example, an array of 10 32-bit integer variables, with indices 0 through 9, may be stored as 10 words at memory addresses 2000, 2004, 2008, … 2036, so that the element with index i has the address 2000 + 4 × i. Because the mathematical concept of a matrix can be represented as a two-dimensional grid, two-dimensional arrays are also sometimes called matrices. In some cases the term "vector" is used in computing to refer to an array, although tuples rather than vectors are more correctly the mathematical equivalent. Arrays are often used to implement tables, especially lookup tables; the word table is sometimes used as a synonym of array. Arrays are among the oldest and most important data structures, and are used by almost every program. They are also used to implement many other data structures, such as lists and strings. They effectively exploit the addressing logic of computers. In most modern computers and many external storage devices, the memory is a one-dimensional array of words, whose indices are their addresses. Processors, especially vector processors, are often optimized for array operations. Arrays are useful mostly because the element indices can be computed at run time. Among other things, this feature allows a single iterative statement to process arbitrarily many elements of an array. For that reason, the elements of an array data structure are required to have the same size and should use the same data representation. The set of valid index tuples and the addresses of the elements (and hence the element addressing formula) are usually, but not always, fixed while the array is in use. The term array is often used to mean array data type, a kind of data type provided by most high-level programming languages that consists of a collection of values or variables that can be selected by one or more indices computed at run-time. Array types are often implemented by array structures; however, in some languages they may be implemented by hash tables, linked lists, search trees, or other data structures. In computer science, an array type is a data type that is meant to describe a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time by the program. Such a collection is usually called an array variable, array value, or simply array.[1] By analogy with the mathematical concepts of vector and matrix, array types with one and two indices are often called vector type and matrix type, respectively. subscribe to random aspirer and visit https://www.nandeeshtank.blogspot.com for more stuff.
