python学习——super()方法实现类的继承

class People(object):
def __init__(self, name, age):
self.name = name
self.age = age

def change_age(self, newage):
self.age = newage
print('{0}的年龄是{1}'.format(self.name, self.age))

class Man(People):
def __init__(self, name, age, email, phone):
super(Man, self).__init__(name, age)
self.email = email
self.phone = phone

def change_email(self, newemail):
self.email = newemail
print('{0}的邮箱是{1}'.format(self.name, self.email))

a = Man('sun', 18, '111@qq.com', '188888888')
a.change_age(20)
a.change_email('222@qq.com')

sun的年龄是20
sun的邮箱是222@qq.com
