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

Question

这个问题来自以下问题,我们说class B延伸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()

会调用do_work父类看到的函数B- 也就是说A.do_work.

super(A,self).do_work()

将调用do_work父类看到的函数A- 即object.do_work(可能不存在,因此可能引发异常).
