Run python script in RPi2 from ssh session

[marciokoko]

If I run a python script on a RPi2 from an ssh session, that script stops once the ssh session is terminated.  How do I make that python script run in the RPi2 indefinitely and irrespective of what happens with the ssh session?  Just run it from the local pi user?  I don't have a monitor on my pi so is there a way to make it run as local from a remote computer?
