inspect.getmembers(module, inspect.isclass), but this uses dir() internally.
You may have to remove imported classes:

>>> def getclasses(module):
...     def accept(obj):
...             return inspect.isclass(obj) and module.__name__ == 
obj.__module__
...     return [class_ for name, class_ in inspect.getmembers(module, 
accept)]
...
>>> getclasses(inspect)
[<class 'inspect.ArgInfo'>, <class 'inspect.ArgSpec'>, ...]
