string - Filtering objects from lists in python -

i'm trying program filter vowels out of string of text , i'm not sure why function doesn't work. here's code

def anti_vowel(text):  letters = text.split() #make list of letters in string  index = 0 #for del  x in letters:      if x == "a" or x == "a" or x == "u" or x == "u" or x == "i" or x == "i" or x == "o" or x == "o" or x == "e" or x == "e":          del letters[index]      index += 1 #to make if-clause work  return "".join(letters) #turn edited list string 

while iterating on letters if-clause should activated when object in letters vowel right? should delete object. doing wrong?

your code isn't iterating through letters, it's iterating through words. because text.split() splits text list of whitespace-separated "word" strings.

the next problem you're iterating through list , deleting entries. mutating iterable while iterating through common cause of strange results.

instead, this:

def anti_vowel(text):     return ''.join(filter(lambda x: x.lower() not in 'aeioe', text)) 

result:

>>> anti_vowel('hi name joe') 'h nm s j'
