Python’s Journey: A Brief History and Evolution of Python Programming Language
Python, a widely-used general-purpose, high-level programming language, was initially designed by Guido van Rossum in 1991 and developed by the Python Software Foundation.
The language was conceived in the late 1980s, and its implementation began in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to the ABC language capable of exception handling and interfacing with the Amoeba operating system.
Over the years, Python has seen a steady evolution with the release of several versions, each introducing new features and improvements.
The first version of Python was released by Guido van Rossum in 1991. Since then, there have been major releases roughly every 18 months, with Python 2.0 coming out in 2000 and Python 3.0 in 2008.
Each version brought significant changes and improvements to the language, making it more powerful, flexible, and user-friendly.
Python’s popularity has grown exponentially over the years, thanks to its simplicity, readability, and the vast array of libraries and frameworks it offers.
Today, Python is one of the most popular coding languages, widely used by programmers worldwide, including big tech companies, small businesses, start-ups, and freelancers.
