python类中super()和

单继承时super()和__init__()实现的功能是类似的

class base(object):
    def __init__(self):
        print 'base create'
class childA(base):
    def __init__(self):
        print 'creat A ',
        base.__init__(self)
class childB(base):
    def __init__(self):
        print 'creat B ',
        super(childB, self).__init__()
base = base()
a = childA()
b = childB()

base create
creat A  base create
creat B  base create

区别是使用super()继承时不用显式引用基类。

super()只能用于新式类中
