救护车服务模拟

1. 首先需要定义救护车和服务请求两个类。

class Ambulance:
    def __init__(self, name, location):
        self.name = name
        self.location = location
        self.is_busy = False
    
    def __str__(self):
        return f"{self.name} at {self.location} is {'busy' if self.is_busy else 'free'}"
    

class ServiceRequest:
    def __init__(self, name, location):
        self.name = name
        self.location = location
        self.is_serviced = False
    
    def __str__(self):
        return f"{self.name} at {self.location} is {'serviced' if self.is_serviced else 'not serviced yet'}"

2. 创建一个模拟器类，其中定义了救护车列表和服务请求列表，以及救护车和服务请求的数量。

class AmbulanceSimulation:
    def __init__(self, num_ambulances, num_service_requests, width, height):
        self.num_ambulances = num_ambulances
        self.num_service_requests = num_service_requests
        self.width = width
        self.height = height
        self.ambulances = []
        self.service_requests = []
        
        self.create_ambulances()
        self.create_service_requests()
        
    def create_ambulances(self):
        for i in range(self.num_ambulances):
            name = f"Ambulance {i}"
            x = random.randint(0, self.width)
            y = random.randint(0, self.height)
            ambulance = Ambulance(name, (x, y))
            self.ambulances.append(ambulance)
        
    def create_service_requests(self):
        for i in range(self.num_service_requests):
            name = f"Request {i}"
            x = random.randint(0, self.width)
            y = random.randint(0, self.height)
            request = ServiceRequest(name, (x, y))
            self.service_requests.append(request)

3. 实现模拟器的主要功能，即匹配空闲的救护车和请求服务的服务请求。

class AmbulanceSimulation:
