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. If you have any questions about indexing in Python leave a comment below. In this tutorial we use Python 3.5.0

Python Tutorial : Data Structures (list, dict, tuples, sets, strings)
 
01:02:58
In this video I am going to show How to use different Data Structures in Python 3. The builtins data structures are: lists, tuples, dictionaries, strings, sets and frozensets. Python Strings - 00:00:01 Python Lists - 00:12:33 Python Tuples - 00:22:32 Python Sets - 00:29:22 Python Dictionary - 00:42:58 Python Slice - 00:52:05 Data structures are particular ways of storing data to make some operation easier or more efficient. Lists: ---------------------- A List in Python is a kind of Collection that allows us to put many values in a single “variable”. A collection is nice because we can carry all many values around in one convenient package. So What is a List? List is An ordered set of values: Ordered: 1st, 2nd, 3rd, … Values: can be anything, integers, strings, other lists List values are called elements. A string is an ordered set of characters so it is “like” a list but not exactly the same thing. Tuples: ---------------------- Python Tuples are another kind of sequence that functions similar to a list - they have elements which are indexed starting at 0. But Tuples are "immutable" i.e. Unlike a list, once you create a tuple, you cannot alter its contents. So Tuple is an an immutable sequence which is Very similar to a list but Tuple is created it cannot be changed Format: tuple_name = (item1, item2) Tuples support operations as lists i.e.Subscript indexing for retrieving elements, Also Methods such as index, Built in functions such as len, min, max, Slicing expressions, The in, +, and * operators. Tuples do not support the methods like append, remove insert, reverse, sort. Advantages for using tuples over lists: 1)Processing tuples is faster than processing lists 2)Tuples are safe 3)Some operations in Python require use of tuples list(tuple_var) function: converts tuple to list tuple(list_var) function: converts list to tuple Python Sets: ---------------------- So What are Sets in python?Sets are An unordered collection with no duplicate elements. Sets are Identified by curly braces e.g. {'Max', 'Tom', 'Den'}. Python Sets Can only contain unique elements, Duplicates are eliminated automatically at the time of initialization. Sets have no order and also Sets do not support indexing. Sets in Python can also be be used to perform mathematical set operations like union, intersection, difference and symmetric difference. Python Dictionary: ---------------------- So What are Dictionaries in python? dictionary in python is an associative list or a map. We can think if dictionary as a list of pairs, where the first element of the pair, the key, is used to retrieve the second element, the value.Hence we map a key to a value.Dictionaries are Python’s most powerful data collection. Dictionaries allow us to do fast database-like operations in Python.Dictionaries are like Lists except that they use keys instead of Index to lookup values. Python Slice: ---------------------- So What is Python Slice? A slice 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 #PythonTutorialforBeginners #ProgrammingKnowledge #LearnPython #PythonCourse ----------------------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 ------------------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

In this Pandas tutorial we will learn how to slice & index a dataframe using loc & iloc. There are several methods to select, slice and index rows and columns from Pandas Dataframes. In this tutorial we will learn to select data by row numbers (.iloc) by label (.loc). The iloc method for slicing Pandas dataframe is used for integer-location based indexing / selection by position whereas the loc method for slicing Pandas dataframe can select rows & column by label/index. We will also cover some of the differences between loc and iloc.

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.

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.

Pandas Filter - How to Filter Rows by Condition
 
05:07
Pandas give you many ways to filter your data. In this video, you will learn how to filter your dataframe rows by condition like a boss. What is Pandas? A Python data analysis library If you are looking to sort your data, please see my other video below: https://youtu.be/MwaCzbh9Sd0 We start the video by creating a simple dataframe that contains two columns. One column holds letters and the other holds integers. Pandas Filter Example #1: Here we try to only select the rows that have the letter "a". After the filter is created, we then show how we can apply the filter to your pandas dataframe. The result should only be the rows that have the letter "a". Pandas Filter Example #2: We step the difficulty up one notch. A second filter is created and we then show how it is possible to apply multiple filters on the same dataframe. The conditions applied to each row can be a union of the two filters or one or the other. The last example just stacks another filter on top of the two already applied to the rows. We also show how to do the opposite which could be beneficial at times. These simple examples should give you confidence and motivate you to slice and dice your own data sets.

2.4 Python Data structures - Lists and Tuples
 
11:01
Data structures Data structure is storage format that enables access and modification of data types. • Base types – Integer, Floating point and Complex numbers, Strings • Collection types – Lists, Tuples, Strings, Sets, Dictionaries • Object system – Classes, Modules Lists (class list) are mutable sequences of items of arbitrary types Tuples (class tuple) are immutable sequences of items of arbitrary types. Lists vs Tuples • Lists and strings have many common properties, such as indexing and slicing operations. They are sequence data types. • Tuple is another standard sequence data type which consists of a number of values separated by commas. • It is not possible to assign to the individual items of a tuple, however it is possible to create tuples which contain mutable objects, such as lists. List() function methods list.append(x) list.extend(iterable) list.insert(i, x) list.remove(x) list.pop([i]) list.clear() equal to del a[:] list.count(x) list.sort(key=None, reverse=False) list.reverse() list.copy() equal to a[:] list.index(x[, start[, end]]) Using List as stack • The list methods make it very easy to use a list as a stack, where the last element added is the first element retrieved (“last-in, first-out”). • To add an item to the top of the stack, use append(). To retrieve an item from the top of the stack, use pop() without an explicit index. Using Lists as Queues • It is also possible to use a list as a queue, where the first element added is the first element retrieved (“first-in, firstout”); however, lists are not efficient for this purpose. While appends and pops from the end of list are fast, doing inserts or pops from the beginning of a list is slow (because all of the other elements have to be shifted by one). • To implement a queue, use collections.deque which was designed to have fast appends and pops from both ends. For example: List Comprehensions List comprehensions provide a concise way to create lists. • A list comprehension consists of brackets containing an expression followed by a for clause, then zero or more for or if clauses. The result will be a new list resulting from evaluating the expression in the context of the for and if clauses which follow it. List example [(x, y) for x in [1,2,3] for y in [3,1,4] if x != y] [(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)] Nested List Comprehensions • The initial expression in a list comprehension can be any arbitrary expression, including another list comprehension. • Consider the following example of a 3x4 matrix implemented as a list of 3 lists of length 4: del statement • There is a way to remove an item from a list given its index instead of its value using the del statement. • The del statement can also be used to remove slices from a list or clear the entire list. • This differs from the pop() method which returns a value. Tuples and Lists • Tuples may seem similar to lists, they are often used in different situations and for different purposes. • Tuples contain a heterogeneous sequence of elements that are accessed via unpacking or indexing. Tuples are immutable. • Lists are mutable, and their elements are homogeneous and are accessed by iterating over the list. Tuple packing and reverse packing • Tuple packing: tu1 = 123, 456, ‘Ken‘ • Reverse packing 123, 456, ‘Ken‘ = tu1 Lambda functions • Python's limited support for anonymous functions is the lambda construct. • Anonymous functions are implemented using lambda expressions; however, these are limited in that the body can only be one expression. • Lambda functions can be used wherever function objects are required. They are syntactically restricted to a single expression. Lambda functions • Lambdas are limited to containing an expression rather than statements, although control flow can still be implemented less elegantly within lambda by using short-circuiting, and more idiomatically with conditional expressions. Lambda Expressions • Small anonymous functions can be created with the lambda keyword. This function returns the sum of its two arguments: f1 = lambda a, b: a+b • Example is the anonymous function which squares its input, called with the integer argument: f2 = lambda x: x**2

2nd video in how to teach yourself to manipulate lists in Python. Here teach ourselves to add / insert a word (homework from previous video) and how to replace a word. Previous video link https://www.youtube.com/watch?v=cUkwNx8KByM&t=1s teach yourself tasks: 1 - put this into python as a string. 2 - turn each word into an element in the string 3 - change "rom" amd "romeo" as you want AND / OR change anything else 4 - go onto "gutenburg", get some of the text of a book / play, and do the same thing Romeo / Juliet................... Rom. By the hour of nine. Jul. I will not fail. 'Tis twenty years till then. I have forgot why I did call thee back. Rom. Let me stand here till thou remember it. Jul. I shall forget, to have thee still stand there, Rememb'ring how I love thy company. Rom. And I'll still stay, to have thee still forget, Forgetting any other home but this. Jul. 'Tis almost morning. I would have thee gone- And yet no farther than a wanton's bird, That lets it hop a little from her hand, Like a poor prisoner in his twisted gyves, And with a silk thread plucks it back again, So loving-jealous of his liberty. Rom. I would I were thy bird. Jul. Sweet, so would I. Yet I should kill thee with much cherishing. Good night, good night! Parting is such sweet sorrow, That I shall say good night till it be morrow. [Exit.] Rom. Sleep dwell upon thine eyes, peace in thy breast! Would I were sleep and peace, so sweet to rest! Hence will I to my ghostly father's cell, His help to crave and my dear hap to tell. Exit

Python Tutorial v3.2.5 Lesson 21.1 - Indexing and Slicing Strings
 
15:12
1:41 Skip the introduction to Lesson 21.1 11:39 Skip directly to the Lesson 21.1 Challenge Program Lesson 21.1 introduces indexes and indexing notation as it relates to string variables. String indexing involves pulling out a specific character from a string using that characters index value. Slicing is pulling out a substring, or a small string contained within a larger string. In isolation, these are fairly simple concepts, but become very important when added to lists, for loops, and classes (which will all be addressed in future lessons). 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.

Javascript How To Convert String To Number Tutorial
 
04:01
In this tutorial you’ll learn how to learn how to use JavaScript to convert a string to a number. Don’t forget to subscribe to the Junior Developer Central channel for more videos and tutorials! The solution to converting between strings and numbers is pretty simple and right off the bat in the tutorial i’ll show you how to use the parseInt JavaScript function to be able to quickly and easily convert from a string to a number. There’s a bit more to learn however and we’ll cover the following additional topics in the tutorial like: How to convert string array to number in JavaScript How to convert comma separated string to number in JavaScript How to convert string value to number in JavaScript How to convert a string to a number using JavaScript How to convert string to float number in JavaScript Converting strings to floats is a relatively straightforward process as all you need to use is the parseFloat function in JavaScript. A tricker problem to solve is converting a string with commas to a number in JavaScript. Or a similar issue, is to convert an array of string values to numbers. As a final wrap up to the tutorial we’ll look at how we can work with these types of strings with commas in and how we can deal with them when converting them to numbers. For example, if you had a string representation of a million, the string might come with commas to separate the units to make it easier to read like: “1,000,000”. We’ll cover how to handle these types of strings.

Array map and sort in JavaScript. Codingame: Horse Racing Duals - Solved
 
03:53
Hi! Let's play and solve a puzzle titled "Horse Racing Duals " by Codingame. I'm Anatol and you are watching the Good Parts of the FrontEnd development. The story tells: Casablanca’s hippodrome is organizing a new type of horse racing: duals. During a dual, only two horses will participate in the race. This puzzle teaches you Sorting and working with Arrays and Lists To win at this game it is necessary to try to select two horses with similar strength. So I need to identify the two closest strengths and show their difference with an integer. I declare an array using a "new" statement and set a length of an array. I’m using a "sort" method to sort the array. Put you attention, you need to use an additional function to sort numbers correctly. Otherwise, number 10 follows number 1, but not number 2 Also, I’m using a "map" method to create a new array. This method executes a function with following parameters: current element, an index and an initial array. Both of these methods return an array, therefore I can "chain" them. In addition, I'm using an unary operator "+". This is a shorthand for a "parseInt" operator. Let's dive into the code. My code is available on GitHub https://github.com/e1r0nd/codingame Documentation is available in the Internet https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Array Follow the links if you’re eager to get more.

For...in and Math.abs in JavaScript. Codingame: Temperatures - Solved
 
04:22
Hi! Let's play and solve a puzzle titled "Temperatures" by Codingame. I'm Anatol and you are watching the Good Parts of the FrontEnd development. The story tells: It's freezing cold out there! Will you be able to find the temperature closest to zero in a set of temperatures readings? This puzzle teaches you how to compare a list of values and an Absolute value. To win this game my program must analyze records of temperatures to find the closest to zero. Let’s start with one trick. I have a string of values, separated by whitespaces. I create an array from this string using a "split" operator. I omit brackets and use the backtick (a template literal) instead. This function makes code a bit shorter. Let's use a "for...in" for looping. The "for...in" statement iterates over the enumerable properties of an object. For each distinct property, statements can be executed. Be aware, that for...in should not be used to iterate over an Array where the index order is important. Array indexes are enumerable properties with integer names and there is no guarantee that for...in will return the indexes in any particular order. But this isn't our case. Besides of that I use Math method "absolute". It returns an absolute value derived from a given variable or function. And one more useful shorthand: Logical OR. This means: assign to a variable "a" the value of variable "b". When variable “b” is undefined, use a value of a variable "c".

NumPy Indexing and Slicing Arrays, Boolean Mask Arrays ,  Numpy Python Data Science
 
13:25
In this Python NumPy Tutorial on Data Science, We discuss Numpy Indexing and Slicing Arrays. We Learn Numpy Boolean Indexing. NumPy is the ultimate package for scientific computing with Python. It contains among other things: a powerful N-dimensional array object, tools for integrating C/C++ and Fortran code, sophisticated (broadcasting) functions, useful linear algebra, random number capabilities and Fourier transform. Basic slicing ( 0:32 ) extends Python’s basic concept of slicing to N dimensions. Basic slicing occurs when obj is a slice object (constructed by start:stop:step notation inside of brackets) . NumPy Boolean arrays ( 8:12 ) used as indices are treated in a different manner entirely than index arrays. Boolean arrays must be of the same shape as the initial dimensions of the array being indexed. In the most straightforward case, the boolean array has the same shape. **************************************************************** $$ What is Jupyter Notebook ?
