Python Packages (pypi)
As Pypi has moved to storing files in directories which change depending on the file being stored, it is rather unpleasant to use in a Source: URL. Instead, files.pythonhosted.org can be used as follows (where %srcname
is defined in the sample python spec here).
Source0: https://files.pythonhosted.org/packages/source/e/%{srcname}/%{srcname}-%{version}.tar.gz
