Python to run a piece of code at a defined time every day

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?

you want you python script to run 24/7 and execute specific tasks at specific times? why not have specialized scripts and use crontab (assuming you are on linux) or Taskschd.msc on windows? – Oystercatcher

This depends on your operating system. You'll likely want to use the os and sys packages to invoke the scheduling tool provided by your OS. – Colchicine

If you are running on a windows machine then see this answer #133471 for an alternative for linux cronetab – Barnstorm

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)

Surprising

@Pastille you are welcome, please mark it as correct answer ( because I already have projects using it LOL ) – Surprising

will it behave like a cron? How can I deploy this? – Bolzano

is possible to implemented with something more Cron style? to not leaving the while true and the script active – Asben

Is this solution, under the condition that the computer is on – Cubicle

Answer 2

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
