如何获得模块中定义但未导入的所有类? [英] How do you get all classes defined in a module but not imported?

问题描述

我已经看过以下问题，但并不能完全解决我想要的问题:

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?

特别是，我不希望导入的类，例如如果我有以下模块:

In particular, I do not want classes that are imported, e.g. if I had the following module:

from my.namespace import MyBaseClass
from somewhere.else import SomeOtherClass

class NewClass(MyBaseClass):
    pass

class AnotherClass(MyBaseClass):
    pass

class YetAnotherClass(MyBaseClass):
    pass

如果我像链接问题中所接受的答案一样使用clsmembers = inspect.getmembers(sys.modules[__name__], inspect.isclass)，它将返回MyBaseClass和SomeOtherClass，除了此模块中定义的3之外.

If I use clsmembers = inspect.getmembers(sys.modules[__name__], inspect.isclass) like the accepted answer in the linked question suggests, it would return MyBaseClass and SomeOtherClass in addition to the 3 defined in this module.

如何仅获取NewClass，AnotherClass和YetAnotherClass?

推荐答案

检查类的__module__属性以找出其定义在哪个模块中.

Inspect the __module__ attribute of the class to find out which module it was defined in.
