title: Finding a letter in a list
body: <p>I have a problem that states: Write a function that takes, as an argument, a list and a string,and returns a Boolean based on whether or not all of the letters in the string appear somewhere in the list. Here is what I have so far. </p>
  
  <pre><code>def findLetters(myList, myString):
      for letter in myString:
          if letter in myList:
              return True
      return False
  </code></pre>
