Yes, the overall structure using the 'for' loop was a bit awkward, and
your second attempt using 'any' is much clearer; but I'd say it's
still worth seeing how your original logic failed. It has to do with
the action of the 'break's. Ask yourself, which code block does the
'if <> else: break' contained /within/ your while loop, break you out
of? And which code block does the 'while <> else: break' break you out
of?
One other thing... it's 'you LOSE', not 'you LOOSE'!!!!! (personal pet
peeve ;-) )
