title: checking if the first letter of a word is a vowel
body: <p>I am trying to use python to write a function that checks whether the first letter of a given word, for instance "ball" is a vowel in either uppercase or lowercase. So for instance:</p>
  
  <pre><code>#here is a variable containing a word:
  my_word = "Acrobat"
  
  #letters in vowel as a list
  the_vowel = ["a","e","i","o","u"]
  </code></pre>
  
  <p>How do a check that the first letter in "Acrobat" is one of the vowels in the list? I also need to take into consideration whether it is upper or lowercase? </p>
