python面向对象中的继承关系中，子类对父类的构造方法的调用有两种方法：
父类名.__init__(self,参数) #注意名字是父类 super(本子类名,self)__init__(其他参数) #注意名字是本身子类，而且init后是self之外的参
例子程序代码：
# -*- coding:utf-8 -*-
class Person(object):
__metaclass__=type
def __init__(self,name="Jim"):
"父类的构造方法,包含初始化属性name"
self.name=name
self.flag=False
print "Person",self.name
def call(self):
print self.flag,"name:",self.name
self.flag = not self.flag
class Programmer(Person):
__metaclass__=type
def __init__(self):
"子类的构造方法,调用父类的构造方法,初始化属性flag"
#调用方式1
Person.__init__(self,"DOTJAR")
print "Programmer"
def setName(self,name="prgrmr"):
self.name=name
class Athlete(Person):
__metaclass__=type
def __init__(self,name="PaoZhu"):
"子类的构造方法,调用父类的构造方法,初始化属性flag"
#调用方式2 注意无参
super(Athlete,self).__init__(name)
print "Athlete"
def setName(self,name="athlete"):
self.name=name
coder=Programmer()
coder.call()
coder.setName("dotjar")
coder.call()
print("----------------")
athlete=Athlete()
athlete.call()
athlete.setName("LiuXiang")
athlete.call()
输出为：
Person DOTJAR Programmer False name: DOTJAR True name: dotjar <class '__main__.Programmer'> ---------------- Person PaoZhu Athlete False name: PaoZhu True name: LiuXiang
