Python is a high-level, interpreted programming language that was first released in 1991 by Guido van Rossum. It is an open-source language, which means that the source code is freely available and can be modified and distributed by anyone. Python's syntax is easy to read and learn, making it an ideal language for beginners to learn programming. Python has numerous libraries and frameworks that make it easy to perform complex tasks. Python is a cross-platform language, which means that it can be run on various operating systems, including Windows, Linux, and MacOS. It has a vast community of developers worldwide, who contribute to its development and support.

Python is a versatile language that is used in a wide range of applications like,

• Web Development
• Data Analysis
• Artificial Intelligence
• Scientific Computing
• Game Development
• Automation
• Desktop Applications

In this tutorial you can see how to install python in your system (Windows/ Linux/ MacOS)
