如何在python turtle中创建一次性按钮？

import turtle

class Button(turtle.Turtle):
    def __init__(self, text, x, y, width, height, action):
        super().__init__(shape="square")
        self.penup()
        self.goto(x, y)
        self.shapesize(height / 20, width / 20)
        self.color("white")
        self.write(text, align="center", font=("Arial", 12, "normal"))
        self.onclick(action)

def button_action(x, y):
    print("按钮被点击了！")

button = Button("点击我", 0, 0, 100, 50, button_action)

turtle.mainloop()
