class Dog(object): def __init__(self,name): self.name=name def play(self): print('%s 蹦蹦跳跳的玩'%self.name) class Person(object): def __init__(self,name): self.name=name #补充代码1:编写函数train,输出内容:张三正在训练大黄 def main(): #补充代码2:创建Dog对象,传递参数:"大黄" #补充代码3:创建Person对象,传递参数:"张三" #补充代码4:Person对象调用train函数操作Dog对象 if __name__=='__main__': main()

补充代码1:
```
def train(self, dog):
print('%s 正在训练%s' % (self.name, dog.name))
```
补充代码2:
```
dog = Dog("大黄")
```
补充代码3:
```
person = Person("张三")
```
补充代码4:
```
person.train(dog)
```
完整代码如下:
```
class Dog(object):
def __init__(self, name):
self.name = name
def play(self):
print('%s 蹦蹦跳跳的玩' % self.name)
class Person(object):
def __init__(self, name):
self.name = name
def train(self, dog):
print('%s 正在训练%s' % (self.name, dog.name))
def main():
dog = Dog("大黄")
person = Person("张三")
person.train(dog)
if __name__ == '__main__':
main()
```

优化代码class DeliveryRequest: def __init__(self, name, location, time): self.name = name self.location = location self.time = time class DeliveryStation: def __init__(self, location): self.location = location self.requests = [] def add_request(self, request): self.requests.append(request) def match_deliveryman(self, deliverymen): for request in self.requests: for deliveryman in deliverymen: if request.location == deliveryman.location and request.time == deliveryman.available_time: print(f"您有一个快递将送给{request.name},请您按时送货") print(f"您的快递将由{deliveryman.name}在{request.time}送达,请您按时等候") deliverymen.remove(deliveryman) break class DeliveryMan: def __init__(self, name, location, available_time): self.name = name self.location = location self.available_time = available_time class Dispatcher: def __init__(self, delivery_stations, deliverymen): self.delivery_stations = delivery_stations self.deliverymen = deliverymen def dispatch(self): for station in self.delivery_stations: station.match_deliveryman(self.deliverymen)
可以考虑优化代码的可读性和效率,例如使用列表推导式和更好的命名:
```python
class DeliveryRequest:
def __init__(self, name, location, time):
self.name = name
self.location = location
self.time = time
class DeliveryStation:
def __init__(self, location):
self.location = location
self.requests = []
def add_request(self, request):
self.requests.append(request)
def match_deliveryman(self, deliverymen):
for request in self.requests:
matching_deliverymen = [dm for dm in deliverymen if dm.location == request.location and dm.available_time == request.time]
for deliveryman in matching_deliverymen:
print(f"您有一个快递将送给{request.name},请您按时送货")
print(f"您的快递将由{deliveryman.name}在{request.time}送达,请您按时等候")
deliverymen.remove(deliveryman)
break
class DeliveryMan:
def __init__(self, name, location, available_time):
self.name = name
self.location = location
self.available_time = available_time
class Dispatcher:
def __init__(self, delivery_stations, deliverymen):
self.delivery_stations = delivery_stations
self.deliverymen = deliverymen
def dispatch(self):
for station in self.delivery_stations:
station.match_deliveryman(self.deliverymen)
```
这样,我们使用列表推导式来创建了一个匹配的快递员列表,然后使用一个 for 循环来遍历它。我们也使用更好的变量名来提高代码的可读性。
