你能用Python写一个停车场管理系统的代码吗

当然，这是一个很好的Python项目。这里是一个简单的实现，涵盖了停车场的基本功能：入场、出场和收费。

class Car:
    def __init__(self, license_number):
        self.license_number = license_number

class ParkingLot:
    def __init__(self, capacity):
        self.capacity = capacity
        self.cars = {}

    def is_full(self):
        return len(self.cars) >= self.capacity

    def park(self, car):
        if self.is_full():
            print(f"Parking lot is full, {car.license_number} can't park.")
        else:
            self.cars[car.license_number] = car
            print(f"{car.license_number} parked successfully.")

    def leave(self, license_number):
        if license_number in self.cars:
            self.cars.pop(license_number)
            print(f"{license_number} left the parking lot.")
        else:
            print(f"{license_number} not found in the parking lot.")

    def charge(self, license_number):
        hours = 2
        fee = 10
        print(f"{license_number} needs to pay {hours * fee} for {hours} hours.")

parking_lot = ParkingLot(5)
car1 = Car("123456")
parking_lot.park(car1)
parking_lot.leave("123457")
parking_lot.charge("123456")

这只是一个简单的例子，您可以根据需求进一步完善它，例如添加时间戳，记录停车记录等。
