Question

In Python, given a module X and a class Y, how can I iterate or generate a list of all subclasses of Y that exist in module X?

Answer 1

Here’s one way to do it:

import inspect  def get_subclasses(mod, cls):     '''Yield the classes in module ``mod`` that inherit from ``cls``'''     for name, obj in inspect.getmembers(mod):         if hasattr(obj, '__bases__') and cls in obj.__bases__:             yield obj
