Checking if A is superclass of B in Python
提问by Andz
class p1(object): pass
class p2(p1): pass
So p2 is the subclass of p1. Is there a way to find out programmatically that p1 is [one of] the superclass[es] of p2 ?
所以 p2 是 p1 的子类。有没有办法以编程方式找出 p1 是 p2 的超类 [es] 之一？

using <class>.__bases__ seems to be what you're looking for...
使用 <class>.__bases__ 似乎是你正在寻找的......
>>> class p1(object): pass
>>> class p2(p1): pass
>>> p2.__bases__
(<class '__main__.p1'>,)

Yes, there is way. You can use a issubclassfunction.
是的，有办法。您可以使用issubclass函数。
As follows:
如下：
class p1(object):pass
class p2(p1):pass
issubclass(p2, p1)

Depending on what you're trying to do, the "mro" method can also be useful.
根据您尝试执行的操作，“mro”方法也很有用。

I think you meant to use "class" instead of "def".. :) Anyway, try p2.__bases__
我认为您打算使用“class”而不是“def”.. :) 无论如何，请尝试 p2.__bases__
