History of Python Programming language
Now let's discuss about the facts and history related to Python programming language. In 1980, Guido Van Rossum started the development of python and in December 1989 implementation of python was begun at Centrum Wiskunde and Informatica (CWI) in Netherlands. Python was ultimately released in 1991. The idea of developing Python programming language was taken from ABC programming language, in other words we can say that Python is the successor of ABC programming language. Python 1.0 was released in 1994 with some added features, then in 2000 Python was released with new features and after that Python 3.0 was released in December 2008.
Why it is called Python Programming language?
You might also be wondering how Python got its name. So here is the answer, Python got its name after the name of Monty Python. There is a fact behind the name of python. During the implementation of Python, Guido Van Rossum was reading the published script of famous BBC comedy series that is "Monty Python's Flying Circus". And Van Rossum wanted to choose a mysterious, sort and unique name so he decided to choose the name Python after "Monty Python's Flying Circus" comedy series for their programming language.
