Hi, screen works all the time no need to login, you can use nohup too nohup python &.

Also you can create a service for it if you are running Ubuntu 15.04 or newer you can create a simple systemd service file to run it as follows

Description=A test unit


Put these lines in a file called hello.service in /etc/systemd/system.

Make sure your script file is executable by running sudo chmod +x <full_path_to_script>

Now reload systemd by running sudo systemctl daemon-reload, start the service sudo systemctl start hello.

Now you can check if the service is running or not using sudo systemctl status hello and stop it using sudo systemctl stop hello

I hope this helps you.

Depending on what your script is supposed to do, instead of running it on your computer, you could run it on something like a Raspberry Pi.

You could also run it online. There are various services that allow you to do that relatively easily. However, I don't think many of them will allow you to run a script 24/7 (especially for free) and it is quite likely that even if they did, your script would stop running every time there was a maintenance. You can circumvent this by getting your own server.
