我建立了一个练习海龟库的程序，让用户循环选择哪个形状。但是，在关闭乌龟屏幕或写入 bye 或 exitonclick 命令之前，我无法退出外循环。有什么为什么在关闭它以绘制另一个形状后再次获得window？

Answer 1

Python turtle 模块不愿意关闭并重新打开它是 window。您可以做的是 reset() window。这会给你一个新的空白 canvas 来绘制和重置你的海龟。这是您以这种方式修改的示例代码：

import time
import random
from turtle import Turtle, Screen

screenWidth, screenHeight = 800, 600

def Create_star_with_inside_borders(pointer, screen, BackgroundColor, penColor, color_mix, screenWidth, screenHeight, central_point_x_value, central_point_y_value, length):
    angle = 144

    screen.title('Star')
    screen.setup(screenWidth, screenHeight)  # choosing the screen size
    screen.bgcolor(BackgroundColor)  # making canvas black

    pointer.pencolor(penColor)  # choosing the pen colour
    pointer.fillcolor(color_mix)  # choosing fill shape color
    pointer.pensize(10)  # choosing the size of pen nib

    pointer.penup()  # taking pen away
    pointer.goto(central_point_x_value, central_point_y_value)  # starting point
    pointer.pendown()  # start typing

    pointer.begin_fill()  # begin filling shape

    for _ in range(5):
        pointer.left(angle)
        pointer.forward(length)
        pointer.left(angle / 2)
        pointer.forward(length)

    pointer.end_fill()  # end filling the shape
    pointer.penup()  # taking pen away

pointer = Turtle('turtle')
screen = Screen()

for _ in range(5):
    BackGroundColor = random.choice(['pink', 'black', 'white'])
    penColor = random.choice(['red', 'green', 'blue'])
    ShapeFillingColor = random.choice(['magenta', 'cyan', 'yellow'])

    size = random.randint(50, 250)

    Create_star_with_inside_borders(pointer, screen, BackGroundColor, penColor, ShapeFillingColor, screenWidth, screenHeight, 0, 0, size)

    pointer.hideturtle()  # hide turtle
    time.sleep(5)
    screen.reset()

screen.bye()

它应该运行你的绘图代码五次不同的设置。

I have build a program practicing turtle library and ask the user to choose which shape in a loop
