小明编写一个类实现设置马的品种、年龄、性别及速度，输出相应的语句，请补全代码。
如下代码输出结果为“一匹阿拉伯12岁的公马，在草原上奔跑的速度为50km/h”。
class _____① _____ :
def __init__(self, category, gender, age):
self.category = category
_____②_____
self.age = age
self.speed = 0
def get_descriptive(self):
self.info = "一匹" + self.category + _____③_____ + "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( ④ + "，" + addr + str(self.speed) + "km/h。")
horse = Horse("阿拉伯","公",12)
horse.get_descriptive()
horse.write_speed(50)
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。")
horse = Horse("阿拉伯","公",12)
horse.get_descriptive()
horse.write_speed(50)
