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.
