Python History and Versions

 Python History and  Versions

•  Python laid its foundation in the late 1980s.

•  The implementation of Python was started in December 1989 by Guido Van Rossum at CWI in Netherland.

•  In February 1991, Guido Van Rossum published the code (labeled version 0.9.0) to alt.sources.

•  In 1994, Python 1.0 was released with new features like lambda, map, filter, and reduce.

• On December 3, 2008, Python 3.0 (also called "Py3K") was released. It was designed to rectify the fundamental flaw of the language.

ABC programming language is said to be the predecessor of Python language, which was capable of Exception Handling and interfacing with the Amoeba Operating System.

The following programming languages influence Python:

1. ABC language.
2. Modula-3

Why the Name Python?

 There is a fact behind choosing the name Python. Guido van Rossum was reading the script of a popular BBC comedy series "Monty Python's Flying Circus". It was late on-air 1970s.

Van Rossum wanted to select a name which unique, sort, and little-bit mysterious. So he decided to select naming Python after the "Monty Python's Flying Circus" for their newly created programming language.

 The comedy series was creative and well random. It talks about everything. Thus it is slow and unpredictable, which made it very interesting.

 Python is also versatile and widely used in every technical field, such as Machine Learning, Artificial Intelligence, Web Development, Mobile Application, Desktop Application, Scientific Calculation, etc.
