python定义一个交通工具的类

在Python中，你可以定义一个名为`Vehicle`的类来表示一般的交通工具，这个类可以包含一些通用属性（如品牌、型号、颜色）和方法（如启动、停止、行驶）。下面是一个简单的示例：

class Vehicle:
    def __init__(self, brand, model, color):
        self.brand = brand
        self.model = model
        self.color = color
        self.is_running = False

    # 定义启动方法
    def start(self):
        if not self.is_running:
            print(f"{self.brand} {self.model} is starting.")
            self.is_running = True
        else:
            print("Vehicle is already running.")

    # 定义停止方法
    def stop(self):
        if self.is_running:
            print(f"{self.brand} {self.model} is stopping.")
            self.is_running = False
        else:
            print("Vehicle is already stopped.")

    # 定义行驶方法
    def drive(self, distance):
        if self.is_running:
            print(f"{self.brand} {self.model} is driving {distance} km.")
        else:
            print("Cannot drive, vehicle is not running.")

# 示例使用
my_car = Vehicle("Toyota", "Corolla", "Red")
my_car.start()
my_car.drive(50)
my_car.stop()
