Using tmux you can start a detached process, which is effectively "hidden", and attach it to check its status, as and when you like. If you start it from a terminal, you can even close that terminal session, and subsequently attach to your tmux python process from another terminal ...
This example uses watch as the command to run, but just substitute your python command... It starts the tmux session in an already deteched state.
tmux new -d 'watch -n 1 -d date' To view the current state of the "hidden" (detached) session, just type tmux attach in a Terminal window...
You can also use screen, but I believe tmux may be the better choice, based on the comments in this Unix-&-Linux answerUnix-&-Linux answer...
