Disemvoweled is not working

I wrote this code for the challenge and it doesn't work even though it works in workspaces. Although if I put 'weeeeeeeeeeeeeeeeeeee' in for the word in workspaces is doesn't get rid of all of the e's and the first for loop only runs 22 times on that word then quits. I don't know why.

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

Instead of using two loops you could use 'in' to check if lett appears inside vowels, and then remove the letter straight away.

if lett in vowel: <remove lett>

Also the join method don't need the parenthesis on the string that's used to join the sequence.

Hope that'll clear things up for you!
