How can we create Python program which will run even after system shutdown

I have created a Python program which takes 3 to 4 hours to complete its execution when I run it interactively.

Is there any way to run this program in Batch(Background) ?... i.e. Even when I shutdown my machine it will run as expected.

Thanks for the answers.

I had to read Log file and if any error finds, had to send an email with Error Log.

I have done it through below :

- Created a Python program
       : Scheduled it to run every 5 mins
       : Which will scan log file for Error Code
       : If Error Code finds send an email to team with error log
- Deployed program on PCF(Pivotal App Cloud Foundry Server).
- Program runs as per given time frame and works correctly.

If you are running the program remotely on a server then you may run it via using the & flag, as such

python file.py &

this keeps the program running even if the terminal is closed, you can also do 

nohup python file.py &

this will write the ouputs(print statements, errors) to nohup.out,

nohup python file.py > myout.out &

you may do this to redirect this output to any file of your choice, rather than nohup.out

I assume this is what you want, since running a program even if a machine is shut doesn't make sense

You can use windows task scheduler, simply set up time trigger or a startup trigger and the action should be your python file.
