- 建立一個(gè)汽車類Auto，包括輪胎個(gè)數(shù)零院，汽車顏色，車身重量村刨，速度等屬性告抄，并通過不同的構(gòu)造方法創(chuàng)建實(shí)例。至少要求 汽車能夠加速 減速 停車烹困。 再定義一個(gè)小汽車類CarAuto 繼承Auto 并添加空調(diào)玄妈、CD屬性，并且重新實(shí)現(xiàn)方法覆蓋加速髓梅、減速的方法
class Auto:
bdef __init__(self, tyre, color, weight, speed):
self.tyre = tyre
self.color = color
self.weight = weight
self.speed = speed
def accelerate(self):
print('speed is up to', speed+30)
def slow_down(self):
print('speed is reduce to', speed-30)
def car_stop(self):
print('the car is stopped')
class CarAuto(Auto):
def __init__(self, air_condition, cd):
super(CarAuto, self).__init__()
self.air_condition = air_condition
self.cd = cd
def accelerate(self):
print('speed is up to', speed+20)
def slow_down(self):
print('speed is reduce to', speed-20)
- 創(chuàng)建一個(gè)Person類拟蜻，添加一個(gè)類字段用來統(tǒng)計(jì)Perosn類的對(duì)象的個(gè)數(shù)
class Perosn:
count = 0
def __init__(self):
Person.count += 1
def __del__(self):
Person.count -= 1
- 創(chuàng)建一個(gè)動(dòng)物類，擁有屬性：性別枯饿、年齡酝锅、顏色、類型 奢方，
class Animal:
def __init__(self, gender, age, color, species):
self._gender = gender
self._age = age
self._color = color
self._species = species
@property
def gender(self):
return Animal.__name__+'的對(duì)象:性別-'+self._gender
@property

def color(self):
return Animal.__name__+'的對(duì)象:顏色-'+self._color
@property
def species(self):
return Animal.__name__+'的對(duì)象:類型-'+self._species
要求打印這個(gè)類的對(duì)象的時(shí)候以'/XXX的對(duì)象: 性別-? 年齡-? 顏色-? 類型-?/' 的形式來打印
- 寫一個(gè)圓類搔扁， 擁有屬性半徑、面積和周長(zhǎng)蟋字；要求獲取面積和周長(zhǎng)的時(shí)候的時(shí)候可以根據(jù)半徑的值把對(duì)應(yīng)的值取到稿蹲。但是給面積和周長(zhǎng)賦值的時(shí)候，程序直接崩潰鹊奖，并且提示改屬性不能賦值
class ReadonlyError(Exception):
def __str__(self):
return '該屬性不能賦值'
class Circle:
def __init__(self):
self.redius = redius
self._area = 3.1415926*self.redius**2

@area.setter
def area(self, value):
raise ReadonlyError
@property
def girth(self):
return self._girth
@girth.setter
def girth(self, value):
raise ReadonlyError
- 寫一個(gè)撲克類苛聘， 要求擁有發(fā)牌和洗牌的功能(具體的屬性和其他功能自己根據(jù)實(shí)際情況發(fā)揮)
import colorama
print(colorama.Fore.MAGENTA)
