Introduction of Python Programming

Introduction of Python Programming

Introduction Python: Python language is a powerful general purpose high level object oriented programming language. Python features simple syntax and a powerful standard library. Python has a large and active developer community, which contributes to the rapid development of the language and extensive documentation.

Python is used in a variety of areas from web development and data analysis to machine learning and software development. Python Language developed by Guido van Rossum in 199.

History of Python Programming Language

• Python was developed by Guido van Rossum in 1991 National Research Institute for Mathematics and Computer Science in the Netherlands.
• The first version of Python 0.9 was released in February 1991. It included support for the basic principles of object-oriented programming.
• Version 1.0 was released in January 1994 featuring functional programming tools features such as support for complex numbers etc.
• Python 2.0 was released in October 2000. It included many new features such as collections, garbage collection, and Unicode support.
• Python 3.0 was developed to fix design flows in the language and remove redundancies. It is not backwards compatible with Python 2.0.
• After the release of version 3.0 the Python Software Foundation continued to maintain. As of today Python 3.14.2 is the current stable version improved syntax and performance. It also introduced new features and optimizations.

Features of Python Programming Language

• Simple: Python is very simple and easy to learn.
• Platform Independent: Python is called platform independent because a Python program can be run on different kind of platform.
• Object Oriented: Python language supports object oriented programming structure so it is called object oriented.
• Dynamic Typing: Python variable data types are determined automatically during python program execution allowing you to write code.
• Flexible: An application developed in python can be modified as per user requirement so it is called flexible programming language.
• Standard Library: Python modules for working with files Internet protocols, strings, databases and much more packages.
• Simplicity: Python syntax is very easy to read making python is simple to develop and maintain source code.
• Interpreted: Python code is executed the interpreter without the need for preliminary compilation.
• Portable: A Python program written in one system can be run in any other system. In simple a Python program can be transferred from one system to another.

Application of Python Programming

• Web Application using python.
• Software development
• Database GUI Application
• Scientific and Numeric Computing
• Business Applications
• Console Based Application

Why Use Python Language

• It is very simple and easy to learn. It powerful, fast and secure. It has very simple syntax. It is powerful scripting language.
• Easy to Learn & Read: Python language syntax is clean, simple, and almost like English.
• Web development (Django, Flask)Data science & visualization (Pandas, NumPy, Matplotlib).
• Machine Learning: Python language can be used modern AI frameworks are built around in Python. If you're interested in AI, deep learning than you can use python programming.

How to Run Python Program in IDLE

Download latest Python: For downloads visit the link:
https://www.python.org/downloads/

Install it onto your system.

Now go to start and search: IDLE

After that you will get an Editor like this:

Now write code and Press Enter to execute.

Run Program in Command Prompt

Download latest Python: For downloads visit the link:
https://www.python.org/downloads/

Install it onto your system.

Now open any editor, write python code and save it into your system directory with .py extension.
Example: D:/pythonpro/program.py.

program.py file:

Now go to start search :cmd

After that you will get a window link this:

Now go to the directory where you have stored your python file and execute it like this:

How to Run Python in Visual Studio Code

Download latest VsCode: For downloads visit the link:
https://code.visualstudio.com/download

Install it onto your system.

After that run your code in VsCode:

How to Write First Program in Python

It is very simple to write and execute any Python Program.

Python Program can be executed directly in the command line .

print("Hello World") print("Welcome To Jiocoding") ============OUTPUT============ Hello World Welcome To Jiocoding

What is Indentation in Python

C Language ,C++ Language and Java languages use braces to indicate blocks of code for class and function definitions or flow control.

But Python uses indentation to indicate a block of code. We can use at least one space for indentation.

How to Write Indentation Program

int x=50 int y=30 if x>y: print("x is greater than y")     else:     print("x is not greater than y") ============OUTPUT============ else: ^ IndentationError: unindent does not match any outer indentation level

You can use number of spaces for indentation but spaces must be same in the same block of code.

How To Write Without Indentation Program

x=50 y=30 if x>y:     print("x is greater than y") else:     print("x is not greater than y") ============OUTPUT============ x is greater than y
