Well, but for an existing library in C++ possibly SWIG will be the 
easiest way to go; since you already have a header file, it might be 
enough to do

swig -python -c++ myheader.hpp

to get the wrappers generated. This works well in simple cases. For 
complicated cases like trying to wrap large template libraries like STL 
or Boost, it is also necessary to twiddle with SWIGs interface language. 
In many cases, however, this can be #ifdef'ed in the header file itself, 
therefore it is easy to keep the interface in sync with the class library.
