title: How to find out the words begin with vowels in a list?
body: <pre><code>words = ['apple', 'orange', 'pear', 'milk', 'otter', 'snake', 'iguana',
           'tiger', 'eagle']
  vowel=[]
  for vowel in words:
      if vowel [0]=='a,e':
          words.append(vowel)
      print (words)
  </code></pre>
  
  <p>My code doesn't right, and it will print out all the words in the original list.</p>
