Simpler answer to challenge

I did this prior to watching the challenge answer. Granted, I could move the vowels into a constant, but I was surprised at the unnecessary complexity in the answers that I have seen. Leveraging Python's incredible simplicity is important, I think.

def strip_vowels(word):
  new_word = ""
  for letter in word:
    if letter.lower() not in ['a','e','i','o','u']:
      new_word += letter
  return new_word.capitalize()
strip_vowels("California")

You don't need the list, you can check for membership in a string.

def strip_vowels(word):
    new_word = ''
    for letter in word:
        if letter.lower() not in 'aeiou':
            new_word += letter
    return new_word.capitalize()

EDIT: Removed unnecessary stuff here.

You are absolutely correct about looping through strings! Didn't even think of that.

The letter.lower() in your code and mine are identical, I don't understand that point your trying to make here (I get why we would change the letter to a known case for testing, else we would need to test the upper case equivalents as well. Neither of us are doing that, however).

As for new_word.capitalize(), your challenge listed as a requirement (at around 5:12 in the video) to return the word capitalized, so I did that.

Thank you for taking the time to respond.

It hasn't been entirely too long since I wrote this challenge for me to remember all that's required for it... No, not at all. :)

I understand completely. I just want to make sure anyone that looks on doesn't get confused by conflicting information.
