- 建立一个汽车类Auto，包括轮胎个数，汽车颜色，车身重量，速度等属性，并通过不同的构造方法创建实例。至少要求 汽车能够加速 减速 停车。 再定义一个小汽车类CarAuto 继承Auto 并添加空调、CD属性，并且重新实现方法覆盖加速、减速的方法
class Auto:
def __init__(self, tyre_num, color, speed):
self.tyre_num = tyre_num
self.color = color
self.speed = speed
def speedup(self, num):
self.speed += num
def speed_down(self, num):
self.speed -= num
if self.speed < 0:
self.speed = 0
def stop(self):
self.speed = 0
class CarAuto(Auto):
def __init__(self, tyre_num, color, speed, air_condition, cd):
super().__init__(tyre_num, color, speed)
self.air_condition = air_condition
self.cd = cd
def speedup(self, target):
if self.speed < target:
self.speed = target
else:
raise ValueError
def speed_down(self, target):
if self.speed > target:
self.speed = target
else:
raise ValueError
- 创建一个Person类，添加一个类字段用来统计Perosn类的对象的个数
class Person:
num = 0
def __init__(self):
Person.num += 1
- 创建一个动物类，拥有属性：性别、年龄、颜色、类型 ，
要求打印这个类的对象的时候以'/XXX的对象: 性别-? 年龄-? 颜色-? 类型-?/' 的形式来打印
class Animal:
def __init__(self, gender, age, color, type):
self.gender = gender
self.age = age
self.color = color
self.type = type
def __repr__(self):
return '/{}的对象:性别-{} 年龄-{} 颜色-{} 类型-{}/'.format(Animal.__name__, self.gender, self.age,
self.color, self.type)
animal = Animal('雄性', 3, '黑色', '中华田园犬')
print(animal)
- 写一个圆类， 拥有属性半径、面积和周长；要求获取面积和周长的时候的时候可以根据半径的值把对应的值取到。但是给面积和周长赋值的时候，程序直接崩溃，并且提示改属性不能赋值
class WriteError(Exception):
def __str__(self):
return 'This Value Read Only!'
class Circle:
def __init__(self, radius: int):
self.radius = radius
self._area = None
self._perimeter = None
@property
def area(self):
return 3.14*self.radius**2
@area.setter
def area(self, value):
raise WriteError
@property
def perimeter(self):
return 2*self.radius*3.14
@perimeter.setter
def perimeter(self, value):
raise WriteError
circle1 = Circle(6)
print(circle1.area, circle1.perimeter) # 113.04 37.68
circle1.area = 300 # __main__.WriteError: This Value Read Only!
circle1.perimeter = 80 # __main__.WriteError: This Value Read Only!
- 写一个扑克类， 要求拥有发牌和洗牌的功能(具体的属性和其他功能自己根据实际情况发挥)
