Python利用海龟画图turtle库做一个篮球比赛计时画面

Python利用海龟画图turtle库做一个篮球比赛计时画面，代码如下

import turtle
import time
import random
r = random.random()
g = random.random()
b = random.random()
turtle.speed(0)
for j in range(1,2,1):for i in range(1,60,1):print(i)time.sleep(0.1)turtle.color(r,g,b) #这是在设置颜色turtle.clear()turtle.hideturtle()turtle.penup()turtle.goto(0, 0)turtle.pendown()turtle.write('篮球比赛计时',align='center',font=('楷体',100,'normal'))turtle.penup()turtle.goto(60, -350)turtle.pendown()if(i<10):turtle.write('0'+str(j)+':0'+str(i),align='center',font=('楷体',300,'normal'))else:turtle.write('0'+str(j)+':'+str(i),align='center',font=('楷体',300,'normal'))
turtle.clear()            
turtle.write('计时结束',align='center',font=('楷体',100,'normal'))

效果如下
