python 的继承 直接调用父类方法及super

class Person(object):
    def __init__(self,name):
        self.name = name
    def getname(self):
        print self.name

class Student(Person):
    def __init__(self,name,age):
        #Person.__init__(self,name)
        super(Student,self).__init__(name)
        self.age = age

s = Student('wyj',18)
s.getname()

class Person:
    def __init__(self,name):
        self.name = name
    def getname(self):
        print self.name

class Student(Person):
    def __init__(self,name,age):
        Person.__init__(self,name)
        self.age = age

s = Student('wyj',18)
s.getname()

在使用super时记得给基类继承object，否则会出错。
