Code works in terminal but TH won't accept. Any ideas?

Hi,

I have run into a problem a few times where I can run my code in terminal yet it won't run here.

Can anyone help to highlight where I am going wrong here?

disemvowel.py 
def disemvowel(word):
    word = word.lower()
    word = list(word)
    vowels = ["a", "e", "i", "o", "u"]
    for vowel in vowels:
        if vowel in word:
            word.remove(vowel)
    word = ''.join(word)
        return word

Hi there! You're doing great but there are a couple of things going on here. First, your indentation is off for your return line. But the biggest problem here is the data set you're testing. Because you are mutating the iterable you're looping over, some checks are being skipped entirely. Check out what happens if you include this line:

print(disemvowel("Treehouse is awesome"))

What is printed to the screen is: trehse s wesome, which obviously still contains vowels. Also, the original capitalization of the word should remain unchanged. What I would expect to get back is Trhs s wsm.

I once left a rather lengthy explanation about what happens to the indexing when you mutate an iterable you're looping over. Take a look at the explanation and then scroll all the way down for an example in this thread.

Hope this helps! :sparkles:

:bulb: On a side note, just because a piece of code appears to work on your system doesn't mean that it fulfills the requirements of the challenge. Try testing other data sets and try to avoid doing anything not explicitly required by the challenge (such as changing the original casing of the word).

Thanks Jennifer,

appreciate the help. I think given the arg was called "word" I took it to literally be just that.

I'll have another crack!
