Determining Python Requirements After the fact

[billybanana]

OK bit of an oddball question but is there a simple way to determine what the requirements are for a single python script ? I've been developing some scripts to download from some services - and whilst they now all work - I've got a bunch of modules installed over the journey and am running Devine, Freevine etc amongst others all on the same machine.

Can I run my script in a virtual environment and let it give me errors to work out what modules are required ? I'd like to put a requirements file together before I let anything loose on others.

I know cart and horse type question. i should have thought about it first and developed in a separate environment but I just got excited and carried away that eventually got my scripts work

Python IDE's usually can do this as well.
