C++ SWIG Pyton - problems to create interface file

[Steffen Kunze]

Hello 
I am from Germany and I study Information-Technology (2nd semester).
Every three month I have a internship at the DLR (German Aerospace
Center) and in the moment I try to use Python and especially SWIG. My
problem is to write the interface file. I have big problems to write
my own interface file. I know that I have to write the headers and the
functions in there, but I haven`t really found out how. (it´s a cpp
and a header file, where class, a datatype and different functions are
defined.)
Maybe you have time to give me some tips to make an interface file out
of the files on

Thank you!!!
