如何在 n 时间后停止 while 循环? [英] How would I stop a while loop after n amount of time?

问题描述

如果 5 分钟后没有达到我想要的效果，我将如何停止它.

how would I stop a while loop after 5 minutes if it does not achieve what I want it to achieve.

while true:
    test = 0
    if test == 5:
        break
    test = test - 1

这段代码让我陷入无限循环.

This code throws me in an endless loop.

推荐答案

尝试以下操作:

import time
timeout = time.time() + 60*5   # 5 minutes from now
while True:
    test = 0
    if test == 5 or time.time() > timeout:
        break
    test = test - 1

您可能还想在此处添加一个短暂的睡眠，以便此循环不会占用 CPU(例如在循环体的开头或结尾处的 time.sleep(1)).

You may also want to add a short sleep here so this loop is not hogging CPU (for example time.sleep(1) at the beginning or end of the loop body).
