title: Return True if no character in String s is a vowel in Python
body: <p>I've tried looking for answers but none seem to help. I've done:</p>
  
  <pre><code>def noVowel(s):
      'return True if string s contains no vowel, False otherwise'
      for char in s:
          if char.lower() not in 'aeiou':
              return True
          else:
              return False
  </code></pre>
  
  <p>No matter the string, it always returns True.</p>
