title: finding an element from one list in another list in python
body: <p>Is there a way to have two lists named list1 and list2 and be able to look up the position of one entry in another. i.e.</p>
  
  <pre><code>list_one = ["0", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]
  
  list_two = ["h","e","l","l","o"]
  </code></pre>
  
  <p>my aim is to allow the user to enter a word which the program will then convert in a set of numbers corresponding to the letters entries in list_one</p>
  
  <p>so if the user did input hello the computer would return 85121215 (being the position of the entries)</p>
  
  <p>is there a possible way to do this </p>
