Python 3

Python 3 was released in late 2008, to update and fix the built-in design flaws of the prior versions of Python. The main focus of Python 3 development was to clean up the code base and reduce redundancy.

In the beginning, the adoption of Python 3 was a very slow process due to its backward incompatibility with Python 2. Moreover, many package libraries were only available for Python 2. Later, there was an increased adoption for Python 3 as the development team announced that there will be an end of life for Python 2 support and more libraries have been ported or migrated to Python 3.
