Python Version History
Python Software Foundation (PSF) used to support two major versions, Python 2.x & Python 3.x. PSF supported Python 2 because a large body of existing code could not be forward ported to Python 3. So, they supported Python 2 until January 2020, but now they have stopped supporting it.
Python 3.0 was released on December 3rd, 2008. It was designed to rectify certain flaws in the earlier version. This version is not completely backward-compatible with previous versions. However, many of its major features have since been back-ported to the Python 2.6.x and 2.7.x version series. Releases of Python 3 include utilities to facilitate the automation of Python 2 code translation to Python 3.
