Python Packaging Authority (PyPA) PyPA is a working group that maintains many of the relevant projects in Python packaging. They maintain a site at https://www.pypa.io, host projects on github and bitbucket, and discuss issues on the pypa-dev mailing list.
Why are there pypa on github and bitbucket?
Is one the master and the other the mirror?
Or does one host part A and the other hosts part B?
