推荐答案

a href =http://docs.python.org/2/library/functions.html#super =nofollow noreferrer> Python Built-in ，super）可能是一个稍好的调用方法父项初始化：

The use of "super" (see Python Built-in, super) may be a slightly better method of calling the parent for initialization:

# Initialize using Parent
#
class MySubClass(MySuperClass):
    def __init__(self):
        MySuperClass.__init__(self)

# Better initialize using Parent (less redundant).
#
class MySubClassBetter(MySuperClass):
    def __init__(self):
        super(MySubClassBetter, self).__init__()
