Python was created in the late 1980s by Guido van Rossum, who was inspired by the BBC comedy series Monty Python’s Flying Circus. He wanted to create a language that was short, easy to read, and slightly mysterious. Python was officially released in 1991 and has since undergone several updates, with the latest version being Python 3. Python is open-source, meaning it is free to use and distribute, even for commercial purposes.
