The story of Python began during the late 1980s when Dutch programmer Guido van Rossum started working on a new programming language. At that time, many programming languages were either too complicated for beginners or lacked flexibility for professional software development. Guido wanted to create a language that combined simplicity, readability, and power while allowing programmers to write fewer lines of code.
Python was developed as a successor to the ABC programming language. Although ABC introduced several innovative ideas, it was not widely adopted because of its limitations. Guido learned from ABC’s strengths and weaknesses and designed Python to be more practical, extensible, and easier to use for real-world programming.
The first public release of Python, version 0.9.0, was published in February 1991. Even in its early versions, Python included many features that made it unique, such as classes, exception handling, functions, modules, and core data structures like lists, dictionaries, and strings. These features laid the foundation for Python’s future growth.
Over the following decades, Python evolved rapidly through contributions from developers around the world. Each new version introduced performance improvements, better security, additional libraries, and modern language features while maintaining Python’s commitment to readability and simplicity.
Today, Python is maintained by the Python Software Foundation (PSF), a non-profit organization dedicated to supporting the language and its global community. Millions of developers contribute tutorials, libraries, frameworks, documentation, and open-source projects, making Python one of the largest programming ecosystems in existence.

Python was created by Guido van Rossum, a Dutch computer programmer who is widely recognized as the creator of the Python programming language. He began developing Python in December 1989 while working at the Centrum Wiskunde & Informatica (CWI) in the Netherlands. His primary objective was to design a programming language that was easy to learn, highly readable, and powerful enough for professional software development.
Before creating Python, Guido had worked on the ABC programming language. Although ABC introduced several innovative programming concepts, it lacked flexibility and failed to gain widespread popularity. Guido used the valuable lessons learned from ABC to develop Python, eliminating many of its limitations while preserving its simplicity and readability.
The name “Python” was inspired by the British comedy television series Monty Python’s Flying Circus, which Guido enjoyed watching. Contrary to a common misconception, Python is not named after the snake. Guido wanted the language to have a short, unique, and memorable name.
For many years, Guido served as Python’s Benevolent Dictator For Life (BDFL), meaning he had the final authority over important language design decisions. In 2018, he stepped down from this role, and Python is now developed through an open governance model managed by the Python Steering Council and supported by the Python Software Foundation (PSF).
