Plain C before Pyrex/Cython before SWIG.

See
http://jelmer.vernstok.nl/blog/archives/218-bzr-svn-now-with-its-own-Subversion-Python-bindings.html
for some of the reasons why I picked plain C over SWIG. Pyrex/Cython are
also good candidates, especially if you're more familiar with Python
than with C.
