Python is a high-level, interpreted programming language known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991. Python is widely used for web development, data analysis, artificial intelligence, and scientific computing. It is known for its clean and easy-to-understand syntax, making it an ideal language for beginners to learn. Python is also versatile, with a large standard library and a thriving ecosystem of third-party packages.


Python is an object-oriented language, which means it uses objects to store data and methods to manipulate that data. It also supports procedural and functional programming paradigms. Python uses indentation to define code blocks, which makes the code more readable and reduces the need for curly braces or keywords to denote the beginning and end of a block. Python is dynamically typed, which means you don't have to declare the type of a variable when you define it. This makes Python code shorter and more flexible, but it can also lead to potential errors if the variable is used in an unexpected way.
