Use python_requires in setup.py

[dmwyatt]

I haven't yet grokked the seemingly complex build tools for this project, but I was just bitten by the fact that cefpython doesn't support python 3.8.

Is there a reason the python version requirements aren't specified in setup.py with python_requires? Interpreter version constraints should be specified there so the project can't be installed in unsupported python versions unless there's some other reason python_requires can't be used.

Cefpython module will not load on an unsupported python version.

The python_requires feature is relatively recent according to documentation, so I don't think it was available at the time when last cefpython was released (2 years ago).

Right, I know that. My point is that it should not even be installable on an unsupported python version.

I don't think it was available at the time when last cefpython was released (2 years ago).

python_requires was added summer of 2016 to setuptools and pip.

Anyway, it's OK, no project with a limited number of developers can do everything! I was just checking if there was a technical reason that python_requires was not being used.

Is a PR adding python_requires something that you'd be interested in seeing?

Sure, PR is welcome. Thanks.
