如何在不使用 turtle.mainloop() 的情况下停止海龟冻结？
How to stop turtle freezing without using turtle.mainloop()?
当我要求用户输入 turtle 时，turtle 页面冻结。
我曾尝试使用 turtle.mainloop()，但这只会完全停止程序。
有什么方法既可以防止 turtle 页面冻结又可以防止程序停止？
代码如下：
import turtle
import time
import random
def quickshape(sides,size,thickness):
int(thickness)
turtle.width(thickness)
int(sides)
int(size)
angle = 360 / sides
int(angle)
for i in range(sides):
turtle.forward(size)
turtle.right(angle)
def correct_position():
global x
global y
turtle.penup()
x = random.randint(-400,400)
y = random.randint(-250,250)
turtle.setpos(x, y)
def move_alot():
global x
global y
turtle.penup()
x += random.randint(-100,100)
y += random.randint(-100,100)
goes = 1
print("My Doodle .co can draw you lots of shapes, depending on what you ask us!")
print("To make a new set of patterns, close the pattern page... but only when it is drawing.")
print()
print("Before we start, do you want day or night mode?")
while True:
mode = input("Mode: ")
if mode == 'day' or mode[0] == 'd':
print("Day mode it is.")
mode = 'day'
break
elif mode == 'night' or mode[0] == 'n':
print("Night mode it is.")
mode = 'night'
break
else:
print("Hmm... which mode?")
titlename = input("Title: ")
print("Configuring - takes a couple of seconds...")
while True:
turtle.ht()
turtle.tracer(0)
turtle.screensize()
turtle.setup(width = 1.0, height = 1.0)
turtle.title(titlename + " [waiting for input - do not close]")
print("[ pattern",goes,"]")
while True:
try:
sides = int(input("Sides: "))
except ValueError:

else:

print("Warning: >35 sides")
break
try:

turtle.setpos(x, y)

print("We are now drawing...")
turtle.width(thickness)
part = 1
int(part)
for part in range(numshapes):
turtle.penup()
viewpart = part + 1
int(viewpart)
percentage = round(int(viewpart)/int(numshapes) * 100,2)
turtle.title(titlename+" [drawing pattern. "+str(percentage)+"% complete.]")
R = random.random()
G = random.random()
B = random.random()
turtle.color(R, G, B)
x += random.randint(-10,5)
y += random.randint(-5,10)
if int(turtle.xcor()) > 650 or int(turtle.xcor()) < -650 or int(turtle.ycor()) > 500 or int(turtle.ycor()) < -500:
correct_position()
else:
if random.randint(1,45) == 1:
move_alot()
turtle.forward(x)
turtle.left(y)
turtle.pendown()
quickshape(sides,size,thickness)
