python - Getting a TYPE ERROR and dont know how to solve the question

Question

High Schooler here, i need help with a question. I have to count the number of vowels in a sentence and output the total no. of vowels along with the word with the most vowels. But I'm getting TypeError: list indices must be integers or slices, not tuple And cant really figure out how to solve it.

string = 'This is a string'
vowels = 'AaEeIiOoUu'

string = string.split(' ')
for i in enumerate(string):
    word = string[i]
    count = [x for x in word if x in vowels]

print(vowels)
print(len(vowels))

Answer 1

While iterating enumerate it always uses a two-parameter(tuple). One is index and the other is an iterable object. Use a contemporary variable after i to iterate the string.

for i,s in enumerate(string)
