i was't able to figure out the disemvowel challenge question

I tried this but it always misses one vowel

disemvowel.py 
def disemvowel(word):
    word=list(word)
    n=0 
    for letter in word:
        if (len(word)+10)-n>0:        
            if letter=='a':
                word.remove('a')
            elif letter=='e':
                word.remove('e')
            elif letter=='i':
                word.remove('i')
            elif letter=='o':
                word.remove('o')
            elif letter=='u':
                word.remove('u')
            elif letter=='A':
                word.remove('A')
            elif letter=='E':
                word.remove('E')
            elif letter=='I':
                word.remove('I')
            elif letter=='O':
                word.remove('O')
            elif letter=='U':
                word.remove('U')
        else:                
            n+=1    
    return "".join(word)

If you modify an iterable while it is controlling a loop, it can cause items to get skipped over by the loop. To prevent this, use a copy of the iterable to control the loop.

Also, it shouldn't be necessary to perform any tests on the length of the word.

You are right, I remember it was mentioned in the python basics course, I have to go back and review somethings. I am a beginner.
