"Impure" Python modules

Not easily. To create a full list, you will have to download all
packages, and check their respective setup.py files for occurrences
of Extension.

A subset can probably be found by looking at all packages classified
as Programming Language :: C

http://pypi.python.org/pypi?:action=browse&c=181

or Programming Language :: C++

http://pypi.python.org/pypi?:action=browse&show=all&c=183

Of course, some of those may only generate C, or deal with C in
some other sense than being written in it.

HTH,
