在特定时间之前运行Python程序 [英] Run Python Program Until Specific Time

问题描述

我想在jupyter笔记本中运行我的程序，并且该程序在特定时间(例如18:00)停止.我通过while循环和增量索引编写了程序，但是最好使用time参数来编写它.

I want to run my program in jupyter notebook and this program stops at specific time(for example 18:00). I wrote program by while loop and incremental index, but it's better to write it with time parameter.

我每天运行7个小时提到的程序.它必须不间断运行.

I run mentioned program for 7 hours each day. It must run nonstop.

    while(i<500000):
         execute algorithm
         i+=1

但是我想像下面这样运行我的程序:

But I'd like to run my program like bellow:

    while(not 18:00 clock):
         execute algorithm

推荐答案

import datetime

while datetime.datetime.now().hour < 18:
    do stuff...

或

if datetime.datetime.now().hour >= 18:
    return
