class Meta(type):
    def __new__(cls, name, bases, dct):
        new_class = type(name, bases, dct)
        new_class.attr = 100  # add some to class
        return new_class


class WithAttr(metaclass=Meta):
    pass


print(type(WithAttr))
# <class 'type'>

为什么它打印<class 'type'>，但不<class '__main__.Meta'> 打印我对吗，类 WithAttr 是 Meta 的实例？
