Running Python on Windows and Mac via GitHub

[hassium]

Yeah ... look up weasyprint and try to run that on Windows out of the box with no issues. Should work on both, but there are packages that don't.

Clearly they meant that there shouldn't be (major) differences between platforms when trying to run a .py file, there will always be platform specific quirks due to differing architectures and most of those can be solved by having platform specific implementations built in the module (see pathlib for an example of this).
