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 attach to your *tmux python process* from some other 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 answer](http://unix.stackexchange.com/questions/15924/how-to-run-streamripper-and-mplayer-in-a-split-screen-x-terminal-via-a-single-sc/15925#15925)...
