马和骆驼都是哺乳动物，它们都有四只脚，体型也差不多大，我们将在这里为它们编写属于它们各自的类，输出相关语句。
例如：一匹阿拉伯12岁的公马，在草原上奔跑的速度为50km/h。
一匹双峰驼20岁的母骆驼，在沙漠上奔跑的速度为40kmh。
class Horse():
def __init__(self, category, gender, age):
self.category = category
self.gender = gender
self.age = age
self.speed = 0
def get_descriptive(self):
self.info = "一匹" + self.category + str(self.age) + "岁的" + self.gender + "马"
def write_speed(self, new_speed):
self.speed= new_speed
addr = "在草原上奔跑的速度为"
print(self.info + "，" + addr + str(self.speed) + "km/h。")
class Came1( ① ):
def __init__(self, category, gender, age):
super().__init__(category, gender, age)
def write_speed(self,new_speed):
②
addr = "在沙漠上奔跑的速度为"
print( ③ ("马","骆驼") + "，" + addr + ④ + "km/h。")
horse = Horse("阿拉伯","公",12)
horse.get_descriptive()
horse.write_speed(50)
came1 = Came1("双峰驼","母",20)
came1.get_descriptive()
came1. write_speed(40)参考答案
class Horse():
def __init__(self, category, gender, age):
self.category = category
self.gender = gender
self.age = age
self.speed = 0
def get_descriptive(self):
self.info = "一匹" + self.category + str(self.age) + "岁的" + self.gender + "马"
def write_speed(self, new_speed):
self.speed= new_speed
addr = "在草原上奔跑的速度为"
print(self.info + "，" + addr + str(self.speed) + "km/h。")
class Came1(Horse):
def __init__(self, category, gender, age):
super().__init__(category, gender, age)
def write_speed(self,new_speed):
self.speed= new_speed
addr = "在沙漠上奔跑的速度为"
print(self.info.replace("马","骆驼") + "，" + addr + str(self.speed) + "km/h。")
horse = Horse("阿拉伯","公",12)
horse.get_descriptive()
horse.write_speed(50)
came1 = Came1("双峰驼","母",20)
came1.get_descriptive()
came1. write_speed(40)答案解析
评分标准：
（1）Horse；（2分）
