我如何给我的乌龟游戏装上最高分系统？

Question

import turtle
import time
import winsound

from tkinter import Tk, Frame, Menu

win = turtle.Screen()
win.title("Collect Balls! v2.0.20")

win.setup(600, 700)
win.tracer(0)


#Timer

我有一个有点像最高分系统的系统，但它不是最高分，而是写最新的分数。我也创建了一个.txt文件来存储数据，但我无法让它工作。我试着看了其他文章，但也不行。请帮助我

添加一个变量 topscore:

delay = 0.1
score = 0
topscore = 0

最高分是最高分(max)的 score 和当前的 topscore:

topscore = max(topscore, score)
peen.write("Top Score: {}".format(topscore), align="center", font=("Ariel", 20, "bold"))
