I don't still get passing this challenge...

I need some help and explanation..

def disemvowel(word):
    result = ''
    vowels = ['a', 'e', 'i', 'o', 'u']

    for letter in word:
        if letter.lower not in vowels:
            result += letter

    return result

The way you're doing it here is checking if the built-in method, 'lower' of string object '<letter>' can be found in your vowels list. Typing 'i'.lower by itself into the python command line will show you. To call the method lower on your letter, you'll need to add '()' to your method name. So if letter.lower() not in vowels:

1 Answer

Your issue is in letter.lower, lower() is a function, so it should have () double parenthesis at the end.

Change this line:

if letter.lower not in vowels:


if letter.lower() not in vowels:
