title: find first string starting with vowel in LIST Python
body: <p>I am brand new to python - </p>
  
  <p>I have to build a function called <code>'first__vowel'</code>.  ACCEPT a list of strings as input
  and RETURN the first string that starts with a lowercase vowel <code>("a","e","i","o", or "u")</code>. if no string starts with vowel, RETURN the empty string <code>("")</code>.</p>
  
  <p>Can you help build this function.</p>
  
  <p>Thanks</p>
