Python and Scheduling Computation

Python and Scheduling Computation

I wish to schedule a computation to occur after my current computation in
python is finished.
For example I am currently running:
>>> for i in range(2, 5):
... tn.TweetNetwork.create_subnetworks(i)
...
I made a simple mistake and meant to type range(1,5). This has been
running for at least 4 hours and should run for another few. That being
said I do not want to re-execute the loop with the correction and lose all
that has been computed.
As I am not by the computer 24/7, how can I schedule python to execute the
function `tn.TweetNetwork.create_subnetworks(1)?
I use emacs 24.3 and ubuntu 12.04 LTS, let me know if you need more
information. All help is greatly appreciated!
