set does not maintain the order so list(set(listt) ) will not maintain elements order as it is in listt. *May not same as list values in order even when have same values. So may return false mostly.


we don't need to care about the order of a set, if we compare the length of the original input and the length of a set of the original input. converting a string to a set will remove all duplicated characters. word = input() if len(word) == len(set(word)): print('Unique') else: print('Deja Vu')


Lothar thanks, that was a great use of "len()"
