If you are running bash, you can do this:

$ myscript.py &
[1] 30834

$ disown %1

Google for GNU screen. But it probably won't be installed either, if 
nohup isn't.

OK, another alternative is to simulate nohup yourself, using the signal 
module. You might want to read the docs and search the cookbook for 
examples of its use. I think it would be something like:

import signal

signal.signal(signal.SIGHUP, signal.SIG_IGN)
