SERIALIZATION
Serialization. Python provides built-in JSON libraries to encode and decode JSON. In Python 2.5, the simplejson module is used, whereas in Python 2.7, the json module is used. Since this interpreter uses Python 2.7, we'll be using json. In order to use the json module, it must first be imported: There are two basic formats for JSON data.REGULAR EXPRESSIONS
Regular Expressions (sometimes shortened to regexp, regex, or re) are a tool for matching patterns in text. In Python, we have the re module. The applications for regular expressions are wide-spread, but they are fairly complex, so when contemplating using a regex for a certain task, think about alternatives, and come to regexes as a lastresort.
EXCEPTION HANDLING
Exception Handling. When programming, errors happen. It's just a fact of life. Perhaps the user gave bad input. Maybe a network resource was unavailable. Maybe the program ran out of memory. Or the programmer may have even made a mistake! Python's solution to errors are exceptions. You might have seen an exception before.LEARN PYTHON

Objects are an encapsulation of variables and functions into a single entity. Objects get their variables and functions from classes. Classes are essentially a template to create your objects. A very basic class would look something like this: class MyClass: variable = "blah" def function (self): print ("This is a message inside theclass.")
CODE INTROSPECTION
Code introspection is the ability to examine classes, functions and keywords to know what they are, what they do and what they know. Python provides several functions and utilities for code introspection. Often the most important one is the help function, since you can use it to find what other functions do.DICTIONARIES
Dictionaries. A dictionary is a data type similar to arrays, but works with keys and values instead of indexes. Each value stored in a dictionary can be accessed using a key, which is any type of object (a string, a number, a list, etc.) instead of using its index to addressit.
BASIC STRING OPERATIONS astring = "Hello world!" astring2 = 'Hello world!'. As you can see, the first thing you learned was printing a simple sentence. This sentence was stored by Python as a string. However, instead of immediately printing strings out, we will explore the various things you can do to them. You can also use single quotes to assign a string. MULTIPLE FUNCTION ARGUMENTS Powered by DataCamp. It is also possible to send functions arguments by keyword, so that the order of the argument does not matter, using the following syntax.

FUNCTIONS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL learnpython.org is a free interactive Python tutorial for people who want to learn Python, fast. LOOPS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL For loops can iterate over a sequence of numbers using the "range" and "xrange" functions. The difference between range and xrange is that the range function returns a new list with numbers of that specified range, whereas xrange returns an iterator, which is more efficient. (Python 3 uses the range function, which acts like xrange).BASIC OPERATORS
Basic Operators. This section explains how to use basic operators in Python. Arithmetic Operators. Just as any other programming languages, the addition, subtraction, multiplication, and division operators can be used with numbers. MODULES AND PACKAGESPANDAS BASICS
Pandas is a high-level data manipulation tool developed by Wes McKinney. It is built on the Numpy package and its key data structure is called the DataFrame. DataFrames allow you to store and manipulate tabular data in rows of observations and columns of variables. There are several ways to create a DataFrame. One way way is to use adictionary.
HELLO, WORLD!
Hello, World! Python is a very simple language, and has a very straightforward syntax. It encourages programmers to program without boilerplate (prepared) code. The simplest directive in Python is the "print" directive - it simply prints out a line (and also includes a newline, unlike in C). There are two major Python versions, Python 2and
CLASSES AND OBJECTS
Objects are an encapsulation of variables and functions into a single entity. Objects get their variables and functions from classes. Classes are essentially a template to create your objects. A very basic class would look something like this: class MyClass: variable = "blah" def function (self): print ("This is a message inside theclass.")
PARTIAL FUNCTIONS
Partial functions allow one to derive a function with x parameters to a function with fewer parameters and fixed values set for the more limited function. This code will return 8. An important note: the default values will start replacing variables from the left. The 2 will replace x. y will equal 4 when dbl (4) is called.MAP, FILTER, REDUCE

About Interactive Tutorials. learnpython.org is a free interactive Python tutorial - one of the Interactive Tutorials websites.. Interactive Tutorials is a personal project of mine aimed at making everyone in the world be able to learn how to code for free. The servers used to run the tutorials and the time invested in writing tutorials is funded through ads. SETS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL learnpython.org is a free interactive Python tutorial for people who want to learn Python, fast. LISTS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL Lists are very similar to arrays. They can contain any type of variable, and they can contain as many variables as you wish. Lists can also be iterated over in a very simple manner. Here is an example of how to build a list. mylist = mylist.append (1) mylist.append (2) mylist.append (3) print (mylist ) # prints 1 CONDITIONS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL Conditions. Python uses boolean logic to evaluate conditions. The boolean values True and False are returned when an expression is compared or evaluated. For example: x = 2 print (x == 2) # prints out True print (x == 3) # prints out False print (x < 3) # prints outTrue. script.py.
GENERATORS - LEARN PYTHON - FREE INTERACTIVE PYTHON TUTORIAL Generators are used to create iterators, but with a different approach. Generators are simple functions which return an iterable set of items, one at a time, in a special way. When an iteration over a set of item starts using the for statement, the generator is run. Once the generator's function code reaches a "yield" statement, thegenerator
VARIABLES AND TYPES
Powered by DataCamp. There are additional variations on defining strings that make it easier to include things such as carriage returns, backslashes and Unicode characters. These are beyond the scope of this tutorial, but are covered in the Python documentation. Simple operators can be executed on numbers and strings: one = 1 two =2 three
DICTIONARIES
Dictionaries. A dictionary is a data type similar to arrays, but works with keys and values instead of indexes. Each value stored in a dictionary can be accessed using a key, which is any type of object (a string, a number, a list, etc.) instead of using its index to addressit.
REGULAR EXPRESSIONS
Regular Expressions (sometimes shortened to regexp, regex, or re) are a tool for matching patterns in text. In Python, we have the re module. The applications for regular expressions are wide-spread, but they are fairly complex, so when contemplating using a regex for a certain task, think about alternatives, and come to regexes as a lastresort.
MULTIPLE FUNCTION ARGUMENTS Powered by DataCamp. It is also possible to send functions arguments by keyword, so that the order of the argument does not matter, using the following syntax. The following code yields the following output: The sum is: 6 Result: 1. def bar (first, second, third, **options): if options.get ("action") == "sum": print ("The sum is: %d" % (firstEXCEPTION HANDLING
Exception Handling. When programming, errors happen. It's just a fact of life. Perhaps the user gave bad input. Maybe a network resource was unavailable. Maybe the program ran out of memory. Or the programmer may have even made a mistake! Python's solution to errors are exceptions. You might have seen an exception before.* Home (current)
