Answer 2

you passed argument 'hello' that means word ='hello'
word[i] means a single character in the word ='hello' through iteration
word[i] == word.isupper() means you are comparing single character with whole word how this possible?

try this
if word[i].isupper():
indices.append(i)
capital_indexes('HeLlO')
print(indices)
