Finding All Classes That Derive From A Given Base Class In Python

I'm looking for a way to get a list of all classes that derive from a particular base class in Python. More specifically I am using Django and I have a abstract base Model and the

Solution 1:

Asset.__subclasses__() gives the immediate subclasses of Asset, but whether that's sufficient depends on whether that immediate part is a problem for you -- if you want all descendants to whatever number of levels, you'll need recursive expansion, e.g.:

defdescendants(aclass):
  directones = aclass.__subclasses__()
  ifnot directones: returnfor c in directones:
    yield c
    for x in descendants(c): yield x

Your examples suggest you only care about classes directly subclassing Asset, in which case you might not need this extra level of expansion.
