为什么升华文本3在完成后会自动关闭输出窗口

Question

# ColorSpiralInput.py

import turtle
t = turtle.Pen()
turtle.bgcolor('black')
# Set up a list of any 8 valid Python color names
colors = ['red', 'yellow', 'blue', 'green', 'orange', 'purple', 'white', 'gray']
# Ask the user for the number of sides, between 1 and 8, with a default of 4
sides = int(turtle.numinput('Number of sides', 'How many sides do you want (1-8)?', 
4, 1, 8))
# Draw a colorful spiral with the user-specified number of sides
for x in range(360):
    t.pencolor(colors[x%sides]) # Only use the right number of colors
    t.forward(x*3/sides+x)      # Change the size to match number of sides
    t.left(360/sides+1)         # Turn 360 degrees / number of sides, plus 1
    t.width(x*sides/200)        # Make the pen larger as it goes outward

当我在sublime text 3中运行此代码时，程序运行后输出窗口立即关闭。我无法查看结果，然后手动关闭窗口

我已经检查了我的代码，但我没有解释。我写过其他脚本，但我没有遇到编辑器的相同行为

可能是我必须更改一些设置吗

Answer 1

对于在控制台中运行的通用Python turtle，执行的最终语句通常是mainloop()或其变体之一done()或exitonclick()。这将控制权移交给底层tkinter事件处理程序

但是，当在IDE（如IDLE、PyCharm、SublimateText等）下运行时，规则会发生变化，并且不一致。有些人需要最终的mainloop()，有些人不想要，有些人把它变成了禁止操作。下面是我如何编写在控制台下运行的程序：

# ColorSpiralInputurtle.py

from turtle import Screen, Turtle

# Set up a list of any 8 valid Python color names
COLORS = ['red', 'yellow', 'blue', 'green', 'orange', 'purple', 'white', 'gray']

screen = Screen()
screen.bgcolor('black')

# Ask the user for the number of sides, between 1 and 8, with a default of 4
sides = int(screen.numinput('Number of sides', 'How many sides do you want (1-8)?', 4, 1, 8))

turtle = Turtle()
turtle.speed('fastest')  # because I have no patience

# Draw a colorful spiral with the user-specified number of sides
for x in range(360):
    turtle.pencolor(COLORS[x % sides])  # Only use the right number of colors
    turtle.forward(x * 3 / sides + x)  # Change the size to match number of sides
    turtle.left(360 / sides + 1)  # Turn 360 degrees / number of sides, plus 1
    turtle.width(x * sides / 200)  # Make the pen larger as it goes outward

screen.exitonclick()

如果您的IDE拒绝mainloop()、done()和/或exitonclick()，您可以始终使用“告诉用户在查看完您的输出后键入”，并在代码中放入最后的input()调用
