The challenge is asking me to remove the vowels from a user input. I have done that but I am getting EOF errors.

Also, I'm required to look for uppercase and lowercase too but I'm not sure how to incorporate that into this yet. Either way, my code does its job as far as Workspaces tells me. What am I doing wrong here?

Here's the Task: "OK, I need you to finish writing a function for me. The function disemvowel takes a single word as a parameter and then returns that word at the end.

I need you to make it so, inside of the function, all of the vowels ("a", "e", "i", "o", and "u") are removed from the word. Solve this however you want, it's totally up to you!

Oh, be sure to look for both uppercase and lowercase vowels!"

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

print(disemvowel(word))

You have a few problems, the most glaring is that there is no string method 'remove', so you're not going to return anything valid unless you change that. Second, right now you're only checking for lower case vowels, because your vowels array only includes lowercase vowels. You could either add uppercase letters to the vowels array, or just use the .lower() method on each character to convert it to a lowercase. Finally, not to do with functionality, but rather the readability of the code, I would highly recommend you don't call the characters 'vowel' unless you know they're actually vowels. When I read through your code, if I'm just skimming it, I would imagine the vowel variable comes from the vowels array, not the word string. I'd use 'char' or 'letter' instead, it won't have any impact on how the code runs, but it will make your code easier to read.

Here's what I would do:

def disemvowel(word):
    vowels = ['a', 'e', 'i', 'o', 'u']
    disemvowled_word = '' #create an empty string to add all non vowels to
    for char in word:
        if char.lower() not in vowels: #if the lowercase character is not contained in the vowels array
            disemvowled_word+= char #add it to my empty string
    return disemvowled_word
