在Python窗口中重复功能

Question

How do I repeat this turtle function in the window for a certain period of time? This code draws squares in a circular shape and I want it to restart once it is done and to do this for 3min and 30sec.

import turtle
import threading



def draw_square(some_shape):
    for i in range (1,5):
        some.forward(100)
        some.right(90)

def draw_art():
    window = turtle.Screen()
    window.bgcolor("yellow")
    sqr = turtle.Turtle()
    sqr.shape("triangle")
    sqr.color("purple")
    sqr.speed(1.5)
    for i in range(1,37):
        draw_square(sqr)
        sqr.right(10)
    window.exitonclick()

def timed():
    threading.Timer(208.0, printit).start()
    draw_art()

timed()

Answer 1

Here is a way you could do it. In your timed function, you record the start time. You then calculate the end time by adding 3 minutes and 30 seconds to the start time.

In a loop, you can continue drawing while the current time is less than the end time.

from datetime import datetime, timedelta

def timed():
    start_time = datetime.now()
    end_time = start_time + timedelta(minutes=3, seconds=30)
    while datetime.now() < end_time:
        draw_art()

Here are some resources on the python datetime module, it's the go-to module for any kind of time or date operations!
