There is also the pyclbr standard module  
<http://docs.python.org/lib/module-pyclbr.html> that does not load the  
module (just reparses enough of it to get the info needed). So a broken  
import, or any other initialization error, won't hurt.

inspect.getmembers(the_module, inspect.isclass) would do. But this  
requires the module to be importable.
