title: How to check if a string contains a string from a list?
body: <p>I want to check if a string the user inputted contains one of the strings in a list.</p>
  
  <p>I know how to check if the string contains <strong>one string</strong> but I want to know how to check if a string contains either this string, or that string, or another string.</p>
  
  <p>For example, if I am checking the user's input to see if it contains a vowel.. there can be 5 different choices when we're talking about vowels (a, e, i, o, or u). How can I check to see if the string the user inputted has one of those?</p>
