python真是简单到离谱...早知道早点用了...

class Light:
    def __init__(self, id, x1, y1, x2, y2):
        self.id = id
        self.x1 = x1
        self.y1 = y1
        self.x2 = x2
        self.y2 = y2


if __name__ == "__main__":
    # 获取用户输入
    # numbers = int(input().split(','))
    # str_arr = input().split(',')

    # 获取灯的数量
    num_lights = int(input("请输入灯的数量："))

    lights = []
    for _ in range(num_lights):
        # 获取一盏灯的信息
        light_info = input("请输入灯的信息（用空格分隔）：").split()
        light_id, x1, y1, x2, y2 = map(int, light_info)
        light = Light(light_id, x1, y1, x2, y2)
        lights.append(light)

    for light in lights:
        print(light.__dict__)

    print("-------------------------------------")

    lights = sorted(lights, key=lambda l: (l.y1,l.x1))
    for light in lights:
        print(light.__dict__)
