Pretty funny. I really like the intent of this recipe.

Have you considered using other functions of random module, such as choice or sample?

''.join(random.choice(leftHand) for j in range(results.passLen))
''.join(random.sample(leftHand * passLen, passLen))

Thanks obernard :) Haha, the intention of this script was entirely innocent since I am left-handed, however my friend soon pointed out how it would be useful to the right-handed population and hence how it ended up here ;D

I like it it is very cool.

I have a friend who lost his left hand in an industrial accident. Can he use his right hand to type the left-handed password?

<tongue firmly in cheek>

Great example code.
