Start python file everyday at 10pm for 12hours

Question

How can I set up starting of python file everyday at same time but after 12hours stop

This question isn't unclear, they're asking how to set a python script to run every day at 10pm for 12 hours. Could one of the close voters clarify their confusion? — TankorSmash, Jul 03 '16 at 22:19
I'm not one of the close voters, but this question could be interpreted as being OS-specific, so at least specifying which OS would be helpful. — Aya, Jul 03 '16 at 22:58

Use cron to start at same time every day:

In your code, note the time the program starts using datetime.now() and in the main loop of your program, run until it is 12 hours later

You haven't specified your OS, etc., but here's a general approach:

Step 1: Write a python script that terminates after 12 hours. (Trivial -- see this)

Step 2: If you're using ubuntu, you can create a crontab and then do the following:

~$ crontab -e

Which will then open up a text file named "crontab" in nano, vim, whatever.

Step3: Next, append this line to the crontab so that the script executes everyday at 10PM:

0 22 * * * /usr/bin/python /path/to/script.py

If you've programmed the script correctly, then it should terminate after 12 hours.
