Hi, I've finished building out a unified python approach in lang/py. It passes our full Yetus tests in cpython 2.7 and 3.5. I also tested it and passed locally in 3.6, 3.7 and 3.8 as well as pypy 7.2.0 for both 2.7 and 3.6.
The pull request is here: https://github.com/apache/avro/pull/744 I know many people are on holiday or unavailable in the near future, but I would really appreciate some eyes on this if you can find the time. The tests give me some confidence, but the change was a significant lift, as Python3 and Python2 handle bytes and unicode strings in substantially different ways. This gives us a path forward to unifying our python support (I mean, dropping lang/py3 and focusing on one API in one place) as well as managing the sunset of python 2 support altogether. Thank you for your help with this project, either way! - Michael
