Python has had several major versions released over the years. The most widely used versions of Python are currently Python 2.x and Python 3.x. Here is a brief overview of each major version:
Python 1.x: This was the first stable version of Python, released in 1994. It included many of the features that are still present in Python today, such as modules, classes, and exceptions.
Python 2.x: This version of Python was released in 2000 and has been widely used for many years. It includes many new features and enhancements over Python 1.x, such as list comprehensions, a garbage collector, and improved Unicode support. The latest release of Python 2.x is version 2.7, which was released in 2010.
Python 3.x: This is the latest major version of Python, first released in 2008. It includes many new features and improvements over Python 2.x, such as a simplified syntax for handling text and binary data, better support for Unicode, and improved performance. However, it is not backward-compatible with Python 2.x, which has led to some resistance to adoption from the community. The latest release of Python 3.x is version 3.10, which was released in October 2021.
In addition to the major releases, there are also many minor releases and bug-fix releases of Python that are released on a regular basis. These updates often include security patches and bug fixes, as well as new features and improvements.
