如何获取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

我已经看到以下问题，但它并没有让我达到我想要的目的:如何在 Python 中获取当前模块中所有类的列表?

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，我不想要导入的类，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

如果我使用 clsmembers = inspect.getmembers(sys.modules[__name__], inspect.isclass) 就像链接问题中接受的答案所暗示的那样，它会返回 MyBaseClass 和 SomeOtherClass 以及本模块中定义的 3 个.

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.

我怎样才能只得到NewClass、AnotherClass 和YetAnotherClass?

How can I get only NewClass, AnotherClass and YetAnotherClass?

推荐答案

检查类的 __module__ 属性以找出它是在哪个模块中定义的.

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