Answer 1

# you can use set to quickly filter duplicates in a string
def isIsogram(word):
unique_letters = set(word)
length_difference = len(word)-len(unique_letters)
if length_difference == 0:
return (word,True)
else:
return (word,False,length_difference)

print(isIsogram('abcdefghi'))
print(isIsogram('aabbccdd'))
