python_super()标准函数

class A(object):
  def __init__(self):
   print ("enter A")
   print ("leave A")
class B(object):
  def __init__(self):
   print ("enter B")
   print ("leave B")

class C(A):
  def __init__(self):
   print ("enter C")
   super(C, self).__init__()
   print ("leave C")
class D(A):
  def __init__(self):
   print ("enter D")
   super(D, self).__init__()
   print ("leave D")
class E(B, C):
  def __init__(self):
   print ("enter E")
   B.__init__(self)
   C.__init__(self)
   print ("leave E")
class F(E, D):
  def __init__(self):
   print ("enter F")
   E.__init__(self)
   D.__init__(self)
   print ("leave F")
F()

》》》输出

enter F
enter E
enter B
leave B
enter C
enter D
enter A
leave A
leave D
leave C
leave E
enter D
enter A
leave A
leave D
leave F

原因：super对象在搜索命名空间时，其实是基于类实例的mro进行。 本次运算：F E B C D A object
