Fix the Error: Vowel Edition

Your friend is trying to write a function that removes all vowels from a string. They write:

def remove_vowels(string):
    vowels = "aeiou"
    for vowel in vowels[1]:
        string.replace(vowel, "", 1)
    return string

However, it seems that it doesn't work? Fix your friend's code so that it actually does remove all vowels.

Examples

remove_vowels("ben") ➞ "bn"

remove_vowels("hello") ➞ "hllo"
# The "e" is removed, but the "o" is still there!

remove_vowels("apple") ➞ "appl"
# The "e" is removed, but the "a" is still there!

Notes

All letters will be lowercase.
