i think this website explain it

Your code doesn't see different case letters as the same letter. There are some other problems there, but I'll let you to figure them out.

That's a hint, not a kata suggestion. Suggestions for the kata are changes on the description, adding some tests, a new translation, etc.

We mark a message as "Suggestion" to ask the authors and contributors to make some non-critical improvements to a kata.

kata hint != kata suggestion

In English, it depends on the context / spelling as to whether it's a vowel. Sometimes it is, sometimes not.

What is your suggestion for the kata tho? Do you want to suggest some improvement? some change?

for i in sentence: i think you should add : for for loop.
English isn't my first language so maybe some wrong on my expression

i am beginner for program too! i see you solution i think the triple useless in your code ,even delete
vowels = ('a','e','i','o','u') still can pass test.
basically,you use count method by for to count each word of string from input.
so triple in this case seems useless.
