Answer 1

for i in word:
count = word.count(i)
if count > 1:
print('Deja Vu')
else:
print('Unique')

Answer 2

"sammich" . split()
evals to ["sammich"]

Answer 3

Is not the same?

Answer 4

even with Oma Falk's correction...your output is:-

Unique
Unique
Deja Vu
Deja Vu
Unique
Unique
Unique
Don't think that is what you're after is it?
You need to define a function that returns True or False and use that in a print function .

Answer 5

you could take the change made by Oma Falk and in if return true and in the else return false in a function called IsDuplicate(word, letter)
and call the function from the for loop instead of the if

many other ways and styles, happy to discuss more if interested
