I won't say SWIG is better than anything, but how would you use ctypes to  
create an instance of a class with several levels of inheritance, and then  
invoke a virtual method?
You have to mangle all the names (not too bad, can be done in Python  
following the rules) but you also need to find the right function pointer  
in the virtual method table; and that can't be done without processing the  
source code (at least the .h) in order to know the layout and ordering of  
the methods.
Let alone inline functions, templates and #define macros.
