The good news is that the standard SWIG library has already done most of
the work for you.  If you add:

%include std_string.i

...in your .i file, then SWIG automagically (using typemaps) converts
between the STL std::string type and Python strings.

More documentation is here:


...where you'll see similar examples for converting between std::vector
and Python lists, std::map and Python dictionaries, and more.
