End of Support for Python 2.x

[snowman2]

Python 2.7 is reaching End Of Life and will no longer be supported by PSF from 1st January, 2020. In addition, pyproj does not support Python 2.7 on Windows since pyproj 2.x.

python/devguide#344

I am thinking pyproj 2.2.x should be the last version(s) to support Python 2.x.

Any opposition?

I'm not sure if I mentioned this elsewhere for this project, but maybe a python_requires could be added to the setup.py before 2.7 is completely dropped: https://packaging.python.org/guides/distributing-packages-using-setuptools/#python-requires

This way python 2 users should be able to accidentally update to a py3-only version of pyproj.

Definitely going to have to happen. Cython is on the list: https://python3statement.org/
