Whats could be wrong with my code here

vowels = ['aeiou']

def a(lister):
    for state in lister: 
        for letter in vowels : 
            try: 
                while True : 
                    print ("entered while loop") 
                    lister.remove(letter) 
                    print("{}" % (lister)) 
                    continue 
            except : 
                return list

states = [ "california" ] 
new_list = a(states)

You will get better responses if you properly format your code and link to the challenge. I'm not sure exactly what you are trying to accomplish here but the line lister.remove(letter) is attempting to remove all the vowels from the item in your states list at once. This won't remove any letters as the string needs to exactly match.

Hi Nitesh

Looks like you are trying to remove the vowels from each state. Couple of things 1) Don't use a while loop like that where the program has no means to exit. 2) the way your code is right now you have one word in a list called 'aeiou' rather than splitting out the letters like this 'aeiou'.split() which will give you a list like so ['a','e','i','o','u'], which you can than loop around. The way i approach this is that vowels wont change they will always be a,e,i,o,u hence you can do a check for the vowel in each state as it goes around the loop and if the vowel is present remove it.

def a(lister):
  new_list=[]
  for state in lister:
    if 'a' in state:
      state = state.replace('a',"")
    if 'e' in state:
      state = state.replace('e',"")
    if 'i' in state:
      state = state.replace('i',"")
    if 'o' in state:
      state = state.replace('o',"")
    if 'u' in state:
      state = state.replace('u',"")
    new_list.append(state)
  return new_list  

states = [ "california" ] 
print(a(states))
