class A(object):
def __init__(self):
print "enter A"
super(A, self).__init__() # new
print "leave A"
class B(object):
def __init__(self):
print "enter B"
super(B, self).__init__() # new
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"
super(E, self).__init__() # change
print "leave E"
class F(E, D):
def __init__(self):
print "enter F"
super(F, self).__init__() # change
print "leave F"
f = F()
输出：
enter F
enter E
enter B
enter C
enter D
enter A
leave A
leave D
leave C
leave B
leave E
leave F
