Python Tutorial Library

Python is famous as a programming language, and its usage is increasing. This Introductory chapter helps beginner programmers to get started learning about Python programming.

The main focus of this lesson is to describe the introduction of Python programming.

• What is Python?
  
• Some Facts about Python
  
• Python Why? Characteristics and Features of Python
  
• What you can do with Python

Python Installation Steps Described In Details.

• Python Environment Setup On Linux, Windows and MAC OS
  
• Python GUI

Python programming basics explained In detail, with different modes of the interpreter.

• Interactive Mode
  
• Script Mode

Comments are non-executable statements in Python. It means neither the python compiler nor the PVM will execute them. Comments are intended for human understanding, not for the compiler or PVM. Therefore they are called non-executable statements.

• Single-Line and Multi-Line Comment
  
• Docstrings

Indentation in Python refers to the (spaces and tabs) that are used at the beginning of a statement. The statements with the same indentation belong to the same group called a suite.

Keywords are reserved words in Python and used to perform an internal operation. Python Keywords must be in your information because you can not use them as a variable name or any other identifier name.

This lesson describes:

• Python Operators and Operands
  
• Types of Python Operators

In Python, we can check whether a string or character is a member of another string or not using "in" or "not in" operators.

• Python membership operators are described.
  
• A Python Program to demonstrate membership operators.

Python programming Numbers are described in detail.

• Types of Numerical Data Types
  
• Type Conversion (Casting)

A string is usually a bit of text in Python programming that is written to be displayed to users.

Sometimes we need to repeat the string in the program, and we can do this easily by using the repetition operator in Python. The repetition operator is denoted by a '' symbol and is useful for repeating strings to a certain length.

Spaces are also considered as a character inside a string, and sometimes unnecessary spaces in the string cause wrong results. Therefore, such blank spaces should be removed from the string before being used.

Python data types are different in some aspects from other programming languages. It is simple to understand and easy to use. Because Python is interpreted programming language and Python interpreter can determine which type of data is storing, so no need to […]

The variable concept is different in Python compared to other programming languages, and it is explained in this tutorial. In Python, a variable is seen as a tag that is tied to some value.

Variables are identifiers of a physical memory location, which is used to hold values temporarily during program execution.

• Defining Values in Python
  
• Assigning Values To Variables
