If your intent is to allow the user to program a robot using python
then no it's NOT suitable.  There's no builtin way to restrict what
code can do (but Zope might have a way), nor can you force it to pause
after a predetermined amount of time, nevermind making that amount of
time deterministic enough to be fair in a game.

However, if your intent was to have only trusted code then Python would
work fine.  My preference would be for generators (especially once
Python 2.5 is released), but YMMV.
