封装回顾

1:property(get_name,set_name)的使用

class User(object):

    def __init__(self,name,age,gender):
        self.__name = name
        self.__age = age
        self.__gender = gender
    # 私有属性获取方法
    def get_name(self):
        return self.__name

    def set_name(self,name):
        self.__name = name

    def speak(self):
        print("我的名字叫："+ self.__name +"，我的年龄是："+ str(self.__age) +"岁，我的性别是："+ self.__gender)

    name = property(get_name,set_name) # 将get_name,set_name 封装起来可以直接用name来使用

# main
if __name__ == '__main__':
    u1 = User("郑洋洋",56,"女")
    # u1.age = 65
    # u1.name = "楼彭辉"
    # u1.set_name("楼彭辉")
    u1.name = "刘建宏"
    u1.name = "liu"
    print(u1.name)

    u1.speak()

2:另一个变形

class User(object):

    def __init__(self,name,age,gender):
        self.__name = name
        self.__age = age
        self.__gender = gender

    @property
    def name(self):
        return self.__name

    @name.setter
    def name(self,name):
        self.__name = name

    def speak(self):

  # name = property(get_name,set_name)

# import  copy
# main
if __name__ == '__main__':
    pass
    # u1 = User("郑洋洋",56,"女")
    # u1.age = 65
    # u1.name = "楼彭辉"
    # u1.set_name("楼彭辉")
    # u1.name = "刘建宏"
    # print(u1.name)
    # u1.speak()

    # [x for x in range(10)]
    # [x for x in range(10) if x%2==0]
    # ls = []
    # for x in range(10):
    #     if x % 2 == 0:
    #         ls.append(x)
    # print(ls)

    # [x+y for x in range(10) for y in range(10)]
    # for x in range(10):
    #     for y in range(10):
    #         print(x + y)
