Introduction
Python is a versatile and widely-used programming language known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991. Python emphasizes code readability and uses indentation and whitespace rather than braces, making it easy to write and understand.
Python is an interpreted language that does not need to be compiled before running. This makes it highly interactive and suitable for rapid application development, scripting, and prototyping. It has gained immense popularity among programmers and is widely used in various domains, including web development, data analysis, scientific computing, artificial intelligence, and automation.
