python 2 deprecation!

[chfw]

Shall we drop python 2 support beyond 2020?

[chfw]

related to #302, where python filesystem 2 demands unicode file path in python 2.

unicode break flake8

pysetup can be considered

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

GitPython requires Python '>=3.0, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*' but the running Python is 2.7.13

there are python 2 files for GitPython. So not sure why pypy2.7-6.0 would complain

https://pypi.org/project/GitPython/#files

We should cut a branch for Python 2 support and do a final release with Python 2 support, before removing support.

We can use multiple pins, like done with ruamel.yaml, to install older versions that support Python 2 only when required.

[chfw]

Please note this thread too: PyFilesystem/pyfilesystem2#317

[chfw]

this will be a priority in 0.7.0, in which python 3.7 only codes will be introduced, such as typing, f-string and data classes. multi-processing via asyncio are under consideration too.

I dont see a problem with py27 deprecation.

If desupporting an old Python, please ensure that the setup.py uses python_requires so that users on other py versions can keep using the older versions of moban without disruption.
