Introduction to Python for Absolute Beginners

Are you a beginner planning to start your career in the competitive world of Programming? Looking resources for Python as an Absolute Beginner? You are at the perfect place. This Python for Beginners page revolves around Step by Step tutorial for learning Python Programming language from very basics to advanced. Python is a high-level programming language and is widely being used among the developers’ community. Python was mainly developed for emphasis on code readability, and its syntax allows programmers to express concepts in fewer lines of code. Python is a programming language that lets developers work quickly and integrate systems more efficiently.

Why learn Python as an absolute beginner ?

Before exploring Python's basics, data types and other features, let us explore why you should learn Python and how it has made its place in industry.

Basics

Python was developed by Guido van Rossum in the early 1990s and its latest version is 3.7.1, we can simply call it as Python3. Python 3.0 was released in 2008. and is interpreted language i.e it’s not compiled and the interpreter will check the code line by line. These articles can used to learn very basics of Python programming language.

• Python language introduction
• Python 3 basics
• Python The new generation language
• Difference between python 2.x and python 3.x
• Keywords in Python | Set 1, Set 2
• Namespaces and Scope in Python
• Statement, Indentation and Comment in Python

• Structuring Python Programs
• How to check if a string is a valid keyword in Python?
• How to assign values to variables in Python and other languages
• How to print without newline in Python?
• Decision making
• Basic calculator program using Python

Input/Output

Developers often have a need to interact with users, either to get data or to provide some sort of result. Most programs today use a dialog box as a way of asking the user to provide some type of input. While Python provides us with two inbuilt functions to read the input from the keyboard.

raw_input ( prompt )
input ( prompt )

• Taking input from console in Python
• Taking multiple inputs from user in Python

Data Types

Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data. Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes.

• Strings
• List
• Tuples

• Sets
• Dictionary
• Arrays

Variables

Python is not “statically typed”. We do not need to declare variables before using them, or declare their type. A variable is created the moment we first assign a value to it.

• Variables, expression condition and function
• Maximum possible value of an integer in python?
• Global and local variables in python
• Packing and unpacking arguments in python
• End parameter in Python

• Type conversion in python
• Byte objects vs string in python
• Print single and multiple variable
• Swap variable
• Private variables
• __name__ (A Special variable) in Python

Operators

Python has all variety of operators ranging from arithmetic and relational to logical operators. Checkout operators here -

• Basic operator in python
• Logical and bitwise not operator on boolean
• Ternary operator
• Division operator in python
• Operator Overloading in Python
• Inplace and standard operators in python
• Difference between == and is operator in Python

• Operator function in python | Set – 1
• Operator function in python | Set – 2
• Inplace operator | Set -1
• Inplace operator | Set -2
• Logic Gates in Python
• Python | a += b is not always a = a + b
• Python Membership and Identity Operators | in, not in, is, is not

Control Flow

Python programming language provides following types of control flow statements to handle looping requirements.

• Loops
• Loops and Control Statements (continue, break and pass) in Python
• Looping technique in python
• range vs xrange on python
• Programs for printing pyramid technique in python
• Chaining comparison in python
• else with for

• switch function
• Using iteration in python effectively
• Python Itertools
• Python __iter__() and __next__() | Converting an object into an iterator
• Python | Difference between iterable and iterator
• Generators in python
• Generators expression in python

Functions

A function is a set of statements that take inputs, do some specific computation and produces output. The idea is to put some commonly or repeatedly done task together and make a function, so that instead of writing the same code again and again for different inputs, we can call the function. Python provides built-in functions like print(), etc. but we can also create your own functions. These functions are called user-defined functions.

• Functions in Python
• class method vs static method in Python
• Write an empty function in Python – pass statement
• Yield instead of Return
• Return Multiple Values
• Partial Functions in Python
• First Class functions in Python
• Precision Handling
• *args and **kwargs

• Python closures
• Function Decorators
• Decorators in Python
• Decorators with parameters in Python
• Memoization using decorators in Python
• Help function in Python
• Python | __import__() function
• Python | range() does not return an iterator
• Python bit functions on int (bit_length, to_bytes and from_bytes)

Applications
