Allright...

I know your problem...

Actually your code is not wrong. But if you don't use tab and you use some spaces when you want to print the result in if else condition, it will be confused...

Don't use space, just use tab below the terminal or above your keyboard...

Note = It's okay if you wanna use space. But better if you use only one space each of the result...

Answer 2

you are checking if your input is in the variable called "vowels" without actually creating the variable first.

Answer 3

Add this variable list after variable input ch :

vowels = ['a','i','u','e','o']
