如何实现枚举嵌套类的函数？
class A(object):
class B(object):
pass
class C(object):
pass
def enumerate_nested_classes(_class):
return () # need proper implementation instead
assert set(enumerate_nested_classes(A)) == {A.B, A.C}

inspect.getmembers()在inspect.isclass()这里应该有所帮助:
classes = [name for name, member_type in inspect.getmembers(A)
if inspect.isclass(member_type) and not name.startswith("__")]
print(classes) # prints ['B', 'C']
请注意,not name.startswith("__")需要检查以排除__class__- 我怀疑有更简单和更pythonic的方式这样做,如果有人会指出这一点,将不胜感激.
