title: Python: Expected an indented block
body: <p>I thought everything was properly indented here but I am getting an <strong>IndentationError: expected an indented block</strong> at the <strong>else:</strong> statement.  Am I making an obvious mistake here?</p>
  
  <pre><code>def anti_vowel(text):
      new_string = ""
      vowels = "aeiou"
      for letter in text:
         for vowel in vowels:
             if (lower(letter) == vowel):
                 #do nothing
             else:
                 #append letter to the new string
                 new_string += letter
