title: sequence containing at least three consecutive vowels
body: <p>I'm trying to create a function to evaluate if contains at least three vowels consecutively. </p>
  
  <p>I've tried so far:
  ( I don't know how to evaluate if they are consecutive)
  any ideas?</p>
  
  <pre><code>def isConsecutive(word):
      # initialize vowel count
  vCounter = 0
  for letter in word:
      if letter == isVowel(word):  
          vCounter += 1
      else:
          vCounter = 0
  
      if vCounter &lt; 3:    
          return False
  return True
  </code></pre>
  
  <h1>Helper function</h1>
  
  <pre><code>def isVowel(char):
      return len(char) == 1 and char.lower() in 'aeiou'
  </code></pre>
