我有一个奇怪的问题.我有以下代码:

class A:
    def f():
        return __class__()

class B(A):
    pass
a = A.f()
b = B.f()
print(a, b)

输出是这样的:

<__main__.A object at 0x01AF2630> <__main__.A object at 0x01B09B70>

那么我怎样才能获得B而不是第二A呢？

我正在用 Sphinx 记录我的图书馆。我有装饰器logic_object：

class logic_object:
    """Decorator for logic object class.
    """
    def __init__(self, cls):
        self.cls = cls
        self.__doc__ = self.cls.__doc__

我有gravity一个由以下人员装饰的课程logic_object：

@logic_object
class gravity:
    """Basic gravity object logic class.

    :param float g: pixels of acceleration
    :param float jf: jump force
    """
#There is more not important code.
