面向对象的开发步骤
面向对象分析：OOA：以分析对象及对象的行为为主
面向对象设计：OOD：将分析的结果还原为代码
面向对象编程：OOP：通过代码实现需求
面向对象测试：OOT:运行测试功能流程
'''
python中面向对象的案例
'''
class Pet:
'''定义一个宠物的类 '''
def __init__(self,nickname,health):
self.nickname=nickname
self.health=health
def recovery(self,nickname):
self.health+=5
print(nickname,"正在恢复中")
class Person:
'''定义一个人的类 '''
def __init__(self,nickname,health):
self.nickname=nickname
self.health=health
def recovery(self,nickname):
self.health+=8
print(nickname,"正在恢复中")
class PetHository:
'''定义一个宠物医院的类'''
def __init__(self,name):
self.name=name
def treat(self,pet):
if isinstance(pet,Pet):
while self.health<=65:
pet.recovery()
print(self.nickname,"正在治疗")
else:
print(self.nickname,"已经康复了")
else:
print("宠物医院只为宠物治疗")
car=Pet("宠物猫",56)
dog=Pet("宠物狗",45)
mine=Person("人",56)
hp=PetHository()
hp.treat(car)
hp.treat(dog)
hp.treat(mine)
class Person:
'''初始化属性'''
def __init__(self,name):
self.name
def driving(self,traffic_tools,area):
'''驾驶的行为'''
print(self.name,"驾驶的行为被调用")
traffic_tools.travel(area)
class TraffvicTolls:
def __init__(self,name):
self.name=name
def travel(self,area):
print(self.name,"行驶的目的地",self.area)
class Area:
def __init__(self,name):
self.name=name
mine=Person("老张")
car=TrafficTools("奔驰")
area=Area("东北")
mine.driving(car,area)
