disemvowel_2

Althought in PyCharm it works with both upper and lower case words heer the program doesn't accept it

disemvowel.py 
def disemvowel(word):
    word=list(word)
    word_c=[]
    vocals=['a','e','i','o','u']
    for w in word :
        if w.lower() in vocals:
            word.remove(w)
        else:
            word_c.append(w)
    return"".join(word_c)

In Python, it's very important that you don't mutate iterables while you iterate over them. Doing so will cause unexpected results, as it throws off the iteration internally. In your case, the problem line is where you run word.remove(w). This line mutates the iterable that's being iterated over, and the loop will end up skipping values, and different things will slip through. In your case, you don't actually need to remove the letter, but you just need to continue onto the next iteration of the loop
