在pycharm运行：class ParkingSpot: def init(self, spot_id, status='Available'): self.spot_id = spot_id self.status = status def str(self): return f'Spot ID: {self.spot_id} Status: {self.status}' class ParkingLot: def init(self, num_spots): self.spots = [ParkingSpot(i) for i in range(1, num_spots+1)] def park_vehicle(self, spot_id): spot = self.spots[spot_id-1] if spot.status == 'Available': spot.status = 'Occupied' print(f'Spot {spot_id} is now occupied.') else: print(f'Spot {spot_id} is already occupied.') def release_spot(self, spot_id): spot = self.spots[spot_id-1] if spot.status == 'Occupied': spot.status = 'Available' print(f'Spot {spot_id} is now available.') else: print(f'Spot {spot_id} is already available.') def display_spots(self): for spot in self.spots: print(spot)只显示进程已结束退出代码

：这段代码是一个简单的停车场系统，包括两个类：ParkingSpot（停车位）和ParkingLot（停车场）。其中，停车位具有唯一的ID和状态（默认为“Available”），而停车场由停车位组成。停车场具有三个方法：park_vehicle（停车）、release_spot（释放停车位）和display_spots（显示所有停车位信息）。进程已结束退出代码。
