python - Python super(Class, self).method vs super(Parent, self).method

Question

这个问题来自以下问题，假设class B扩展class A

class A(object):
  def do_work(self):
    print 123

class B(A):
  def do_work(self):
    super(B,self).do_work() # versus the next statement
    super(A,self).do_work() # what's the difference?

Answer 1

super(B,self).do_work()

将调用do_work父类所看到的函数B- 即A.do_work.

---

super(A,self).do_work()

将调用-do_work的父类所看到的函数（它可能不存在，因此可能会引发异常）。Aobject.do_work
