You can do that with Cython, too.

I might be a bit biased as a core developer, but if the parts of you C
library's API for which you have an immediate use are not so tremendously
huge that it's entirely infeasible for you to write a nicely usable Python
API for them, I'd always recommend using Cython over a wrapper generator
like SWIG. Once you get to the points where it becomes interesting, you'll
always end up having more fun writing a Cython based integration layer than
fighting your up-hill battle against the way the wrapper generator wants
you to design it.
