如何加速python的'turtle'功能并在最后阻止它冻结 [英] How to speed up python's 'turtle' function and stop it freezing at the end

问题描述

我用python写了一个turtle程序，但是有两个问题.

I have written a turtle program in python, but there are two problems.

1. 对于较大的数字，它的速度太慢了，我想知道如何加快乌龟的速度.
2. 它在完成后冻结，点击时显示无响应"

这是我目前的代码:

import turtle

#Takes user input to decide how many squares are needed
f=int(input("How many squares do you want?"))
c=int(input("What colour would you like? red = 1, blue = 2 and green =3"))
n=int(input("What background colour would you like? red = 1, blue = 2 and green =3"))

i=1

x=65

#Draws the desired number of squares.
while i < f:
    i=i+1
    x=x*1.05
    print ("minimise this window ASAP")
    if c==1:
        turtle.pencolor("red")
    elif c==2:
        turtle.pencolor("blue")
    elif c==3:
        turtle.pencolor("green")
    else:
        turtle.pencolor("black")
    if n==1:
        turtle.fillcolor("red")
    elif n==2:
        turtle.fillcolor("blue")
    elif n==3:
        turtle.fillcolor("green")
    else:
        turtle.fillcolor("white")
    turtle.bk(x)
    turtle.rt(90)
    turtle.bk(x)
    turtle.rt(90)
    turtle.bk(x)
    turtle.rt(90)
    turtle.bk(x)
    turtle.rt(90)
    turtle.up()
    turtle.rt(9)
    turtle.down()

顺便说一句:我使用的是 3.2 版！

By the way: I am on version 3.2!

推荐答案

1. 将 turtle.speed() 设置为 fastest.
2. 使用 turtle.mainloop() 功能无需刷新屏幕即可完成工作.
3. 使用 turtle.tracer(0, 0) 禁用屏幕刷新，然后在最后执行 turtle.update()

1. Set turtle.speed() to fastest.
2. Use the turtle.mainloop() functionality to do work without screen refreshes.
3. Disable screen refreshing with turtle.tracer(0, 0) then at the end do turtle.update()
