Problems with python class inheritance

本问题已经有最佳答案，请猛点这里访问。

我在玩弄Python类继承，但似乎无法让子类正常工作。

我得到的错误消息是：

1	must be a type not classobj

代码如下：

class User():
"""Creates a user class and stores info"""
def __init__(self, first_name, last_name, age, nickname):
self.name = first_name
self.surname = last_name
self.age = age
self.nickname = nickname
self.login_attempts = 0

def describe_user(self):
print("The users name is" + self.name.title() +"" + self.surname.title() +"!")
print("He is" + str(self.age) +" year's old!")
print("He uses the name" + self.nickname.title() +"!")

def greet_user(self):
print("Hello" + self.nickname.title() +"!")

def increment_login_attempts(self):
self.login_attempts += 1

def reset_login_attempts(self):
self.login_attempts = 0

class Admin(User):
"""This is just a specific user"""
def __init__(self, first_name, last_name, age, nickname):
"""Initialize the atributes of a parent class"""
super(Admin, self).__init__(first_name, last_name, age, nickname)

jack = Admin('Jack', 'Sparrow', 35, 'captain js')
jack.describe_user()

我用的是python 2.7
