Description: A pledge to drop Python 2 support by 2020.

Almost all major open source Python packages now support both Python 3.x and Python 2.7, and many projects have been supporting these two versions of the language for several years. While we have developed tools and techniques to maintain compatibility efficiently, it is a small but constant friction in the development of a lot of code.
We are keen to use Python 3 to its full potential, and though we accepted the cost of writing cross-compatible code to allow a smooth transition, we did not intend to maintain this compatibility indefinitely. Although the transition was not as quick as we hoped, it is taking place, with more and more people using, teaching and recommending Python 3.
The developers of the Python language extended support of Python 2.7 from 2015 to January 1, 2020, recognising that many people were still using Python 2. We believe that the extra 5 years was sufficient to transition off of Python 2, and now that upstream support has ended, our projects have stopped supporting Python 2 or will do so before the end of 2020. We will thus be able to simplify our code and take advantage of the many new features in the current version of the Python language and standard library
