如何在Python中动态查找子类的包名？

import inspect

def find_subclass_package(class_name):
    subclasses = []
    for name, obj in inspect.getmembers(sys.modules[__name__]):
        if inspect.isclass(obj) and issubclass(obj, class_name):
            subclasses.append(obj.__module__)
    return subclasses

# 假设我们要查找名为MyClass的子类的包名
class MyClass:
    pass

class MySubClass1(MyClass):
    pass

class MySubClass2(MyClass):
    pass

subclasses_packages = find_subclass_package(MyClass)
print(subclasses_packages)
