If you want Python robot.py & is not possible, once the user log out, the script will automatically exit. With at, Cron can be implemented, but I found a command.

Nohup, can ignore log out of the signal, now as long as

Nohup python robot.py &
Just fine. If you want to record the print in Python, you can

Nohup python robot.py & >/log/log1.log

View Python--pid running in the background

Command:ps-ef |grep python

Find the execution file and its path in Linux based on the PID value of the process

The following commands can be used to manipulate process tasks:
PS Lists the processes that are running in the system
