I like your solution. I used this approach: First I load the input into a list next I used set to convert a copy of the list to a set. Since sets do not allow duplicates I simply compared the len of the set and list to determine if it was deja vu or not.

David Carroll I am going to look that up and try that out. Thanks for sharing that!

s = input() c = 0 for l in s: if s.count(l) > 1: c += s.count(l) c -= int(c/2) if c > 1: print('Deja Vu') else: print('Unique')

Paul K Sadler Another option could be to use the any() function on a sorted list. This can compare the current with the previous positions which will return True as soon as the first match is found. 😉

s = input() c = 0 for l in s: if s.count(l) > 1: c = s.count(l) if c > 1: print('Deja Vu') else: print('Unique')

Uh can use dictionaries also

def checker(text): r = '' for i in text: if r != i: r = i else: return 'Deja Vu' return 'Unique' t = input() print(checker(t))

letters=input() c=[] for i in letters: c.append(1) if letters.count(i)>1 else c.append(0) print('Deja Vu' if sum(c)>=1 else 'Unique' )

With the any() function: l = input() if any([l.count(i) > 1 for i in l]): print("Deja Vu") else: print("Unique")
