Guido van Rossum developed Python, a popular high-level programming language for general-purpose programming, which was originally made available in 1991. Python is an interpreted language with a design philosophy that prioritizes code readability. For example, instead of using curly braces or keywords to delimit code blocks, Python uses whitespace indentation. Python also has a syntax that enables programmers to express concepts in less code than is possible in languages like C++ or Java.

The language offers constructs that should make it possible to write both small- and large-scale programs that are clearly expressed.

Python has a dynamic type system, and automatic memory management, and it supports a variety of programming paradigms, such as procedural, imperative, functional, and object-oriented programming. Its standard library is extensive and complete.

Because Python is so popular and there are interpreters for many different operating systems, Python code may execute on a wide range of platforms. The community-based development model is shared by nearly all of Python's variant implementations, including CPython, the standard implementation. The nonprofit Python Software Foundation is in charge of running CPython.
