There shouldn't be much difference between a Jython or Python
implementation - unless you are building a GUI of course!

Ive no idea how nim is played although I re,em,ber my math
teacher talking about it as being the only practical use
of binary outside computing...

But what kind of help do you need? Does your code work?
Is there an error (if so send us the full text)?
Do you want a general code review?
What exactly do you want from us?
