Sorting in Python  ||  Learn Python Programming  (Computer Science)
 
06:24
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.

How do I sort a pandas DataFrame or a Series?
 
08:57
pandas allows you to sort a DataFrame by one of its columns (known as a "Series"), and also allows you to sort a Series alone. The sorting API changed in pandas version 0.17, so in this video, I'll demonstrate both the "old way" and the "new way" to sort. I'll also show you how to sort a DataFrame by multiple columns at once! New videos every TUESDAY and THURSDAY!

Python Tutorial for Beginners 7 - Python Lists
 
12:45
In this video I am going to show What are Lists and How to use lists in python. 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. The list of all functions which can be use with Python Lists: ['__add__', '__class__', '__contains__', '__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'clear', 'copy', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'] -------------------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/ProgrammingKnowledgeLear... http://fb.me/AndroidTutorialsForBegin... http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter Donate to ProgrammingKnowledge -- (https://www.paypal.com/de/cgi-bin/webscr?cmd=_flow&SESSION=AW9N5aRI7sCqjlIusdmku9rz2uvuULZ6K580uDxTK7ElJs2LHDiLq-TQv0a&dispatch=5885d80a13c0db1f8e263663d3faee8def8934b92a630e40b7fef61ab7e9fe63) python tuples python beginner python beispiel python add list python empty tuple array python example python sequence vs list python find sequence in list python convert list to sequence python escape sequences list python sequence of numbers python string endswith python append to list python join python slice list python compare tuples python dicts python list operator python tupel python empty list

Python Tutorial: Reindexing DataFrames
 
04:36
Second video of the first chapter of our course: Merging DataFrames with pandas by Dhavide Aruliah. First chapter free: https://www.datacamp.com/courses/merging-dataframes-with-pandas As a Data Scientist, you'll often find that the data you need is not in a single file. It may be spread across a number of text files, spreadsheets, or databases. You want to be able to import the data of interest as a collection of DataFrames and figure out how to combine them to answer your central questions. This course is all about the act of combining, or merging, DataFrames, an essential part of any working Data Scientist's toolbox. You'll hone your pandas skills by learning how to organize, reshape, and aggregate multiple data sets to answer your specific questions. Now we can import many files into individual DataFrames, let's investigate sharing information between DataFrames using their Indexes. This is essential for combining DataFrames later, as Indexes are the means by which DataFrame rows are labelled. Let's make a brief note on terminology. The plural of "index" in English can be indexes or indices; both are acceptable. Let's adopt the convention of using indices as the plural of index when referring to individual labels within an Index data structure. By contrast, we can use indexes as the plural of index with reference to many Index data structures associated with several Pandas Series or DataFrames. This is not a standard convention, but it helps us resolve ambiguity in thinking about, say, sets of indices within many indexes. To start, let's load two DataFrames of temperature data recorded from Pittsburgh in 2013. For both calls to read_csv(), we use the index_col argument to specify which column becomes the DataFrame Index ('Month' in both cases). Remember, the Index is a privileged column in Pandas providing convenient access to Series or DataFrame rows. We can examine our DataFrames w_mean & w_max more closely. The Mean TemperatureF & Max TemperatureF columns are respectively the average & maximum daily temperatures (in Fahrenheit) observed during three-month intervals or quarters. For both DataFrames, the column Month is the DataFrame Index. The month listed in each Index row is the first month of each quarter. By virtue of how the CSV files are stored, the Index of w_mean is in alphabetical order while the Index of w_max is in chronological order; the former gives a distorted sense of time-dependent trends. The DataFrame Indexes are accessed directly with the .index attribute. Both w_mean & w_max have Indexes of type object because the index labels are strings. The Pandas type() function shows us the data type of the Index. We define a list called ordered to impose a deliberate ordering for the Index labels of w_mean. The DataFrame .reindex() method creates a new DataFrame w_mean2 with the same data as w_mean but with a new row ordering according to the input list ordered. We can see that w_mean2 has the desired chronological ordering. The original alphabetically-ordered DataFrame can be recovered with the DataFrame .sort_index() method. Pandas Index labels are typically sortable data, such as numbers, strings, or datetimes. The input argument to the .reindex() method can also be another DataFrame Index. For instance, here, we use the Index from w_max to reindex w_mean in chronological order. When a suitably indexed DataFrame is available, the reindex() method spares us having to create a list manually or having to sort the Index. The specific Index labels provided to the .reindex() method are important. For instance, if we invoke .reindex() again using an input list containing a label that is not in the original DataFrame Index (Dec in this case), an entirely new row is inserted & filled with the null value NaN or not-a-number. We can also use .reindex() to see where DataFrame rows overlap. For instance, here, we reindex w_max with the index of w_mean3 showing that w_max does not have a row labelled Dec either. Using .dropna() removes entire rows in which null values occur. This is a common first step when merging DataFrames. Finally, we should realize that order counts. That is, w_max.reindex(w_mean.index) is not the same as w_mean.reindex(w_max.index). The latter fixes the row order as desired in w_mean; the former replicates the misleading alphabetical row order in w_max; this is likely not desired. Try reindexing some DataFrames now in the exercises.

Python Tutorial for Beginners 17 - Python Slice and Negative index
 
10:53
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 #PythonTutorialforBeginners #ProgrammingKnowledge #LearnPython #PythonCourse -------------------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

Quick Sort in Python
 
09:42
QuickSort Like Merge Sort, QuickSort is a Divide and Conquer algorithm. It picks an element as pivot and partitions the given array around the picked pivot. There are many different versions of quickSort that pick pivot in different ways. Always pick first element as pivot.Always pick last element as pivot (implemented below)Pick a random element as pivot.Pick median as pivot. The key process in quickSort is partition(). Target of partitions is, given an array and an element x of array as pivot, put x at its correct position in sorted array and put all smaller elements (smaller than x) before x, and put all greater elements (greater than x) after x. All this should be done in linear time. Partition Algorithm There can be many ways to do partition, following pseudo code adopts the method given in CLRS book. The logic is simple, we start from the leftmost element and keep track of index of smaller (or equal to) elements as i. While traversing, if we find a smaller element, we swap current element with arr[i]. Otherwise we ignore current element.
