Python Python Collections (Retired) Lists Redux Removing Items From A List

if statement failing to target only vowels. I can't see why.

My intention was to print only the vowels, but every letter is being printed not just the vowels.

word_list = ["alphacentauriano"]
vowel_list = []

for word in word_list:
    print(word)
    for letter in word:
        if letter == "a" or "e" or "i" or "o" or "u":
            print(letter, end=" ")

Hi,

The problem is that on line

if letter == "a" or "e" or "i" or "o" or "u":

you are comparing if letter equals to "a" 'or' "e" is true. You are not comparing if letter equals to e. Since the second 'or' comparison is always true, all the letters are printed.

You always need to include the variable when you are comparing it to something, e.q.

if letter == "a" or letter == "e"
