Yes.

I don't know about that, but I do know that I vastly prefer Pyrex to SWIG 
for creating Python-to-C interfaces.  Pyrex is basically Python code with 
the ability to declare and use C variable and function types.  You write 
some very Python-like code, run it through Pyrex, and get C source 
code.  The resulting interface is *much* more Pythonic than what you can 
get in SWIG without extensive typemapping work.  See:
