# Disemvowel Challenge

I don't want to add upper case to my vowel tuple. How do I make this check? I've tried writing an if for letter.upper() but can't seem get anything working. Suggestions? https://w.trhou.se/8gqxir92tn

This:

```def disemvowel(word):
vowels = ("a", "e", "i", "o", "u")
new_word_chars = list(word)
for letter in vowels:
while letter in new_word_chars:
new_word_chars.remove(letter)
new_word_chars.remove(letter.upper())
newWord = "".join(new_word_chars)
word = newWord
return word
```

Doesn't work due to the check in the while loop for only the lowercase letters.

Try instead:

```def disemvowel(word):
vowels = ("a", "e", "i", "o", "u")
new_word_chars = list(word)
for letter in vowels:
while letter in new_word_chars:
new_word_chars.remove(letter)
while letter.upper() in new_word_chars:
new_word_chars.remove(letter.upper())
newWord = "".join(new_word_chars)
word = newWord
return word
```

(By the way, this solution works, but it is more elegant and clean to write:

```def disemvowel(string):
return ''.join([letter for letter in string
if letter not in "aeiouAEIOU"])
```
