How to print in python ?

The print() function in Python is one of the most commonly used tools for displaying output. Whether you're debugging code, showing results, or interacting with users, print() is your go-to function.


print ("Hello world ")



Printing Multiple Items

You can print multiple items separated by commas:

Python Introduction

What is python ?

  • Python is very popular programming language  and this is developed by Guido van  Rossum .

  • This is released in 1991 .

  • Python supports multiple programming paradigms, including procedural, object-oriented, and functional programming

Key characteristics
  • Interpreted: Python code is executed line by line, simplifying debugging and allowing for rapid prototyping.
  • Object-Oriented: It supports object-oriented programming, enabling developers to create reusable and modular code.
  • Dynamically Typed: Python automatically determines variable types during runtime, reducing the need for explicit type declarations and making coding more flexible.
  • High-Level: Python handles complex operations like memory management, allowing developers to focus on problem-solving rather than low-level details.
  • Platform Independent: Python code can run on various operating systems (Windows, MacOS, Linux) without modification, promoting portability.
  • Free and Open-Source: Python is freely available to download, use, and distribute, fostering a large and active community that contributes to its continuous development and extensive library ecosystem. 
Good to know :

The most recent version is python3
