How do you get all classes defined in a module but not imported?

Question

I\'ve already seen the following question but it doesn\'t quite get me where I want: How can I get a list of all classes within current module in Python?

In particul

Answer 1

I used the below:

# Predicate to make sure the classes only come from the module in question
def pred(c):
    return inspect.isclass(c) and c.__module__ == pred.__module__
# fetch all members of module __name__ matching 'pred'
classes = inspect.getmembers(sys.modules[__name__], pred)

I didn't want to type the current module name in
