Python每天在定义的时间运行一段代码

Question

In my python program, I would like it to run a piece of code at a pre-defined time every weekday, let say 2pm Mon - Fri.

How may I do it please?

Answer 1

You can use "schedule" library

to install, on terminal enter:

pip install schedule

here is an example of the code you want:

#!/usr/bin/python

import schedule
import time

def job():
    print("I am doing this job!")


schedule.every().monday.at("14:00").do(job)
schedule.every().tuesday.at("14:00").do(job)
schedule.every().wednesday.at("14:00").do(job)
schedule.every().thursday.at("14:00").do(job)
schedule.every().friday.at("14:00").do(job)

while True:
    schedule.run_pending()
    time.sleep(1)

you can make use of crontab linux utility, Crontab (CRON TABle) is a file which contains the schedule of cron entries to be run and at specified times.

for your question , goto the python file's directory and enter in terminal

crontab -e

then within crontab file you can enter like this , for eecuting at 2.30pm daily

30 14 * * *         python3 your_python_file.py
