title: How to iterate through a file and create new string variables by line
body: <p>I read through docs, but still cannot figure out how to open a file, read each line, store that line as a new string variable (for now). </p>
  
  <p>I tried:</p>
  
  <pre><code>file = file.open ("users.txt", r)
  
  for user in users:
      user = users.readline ()
      ''' this is where I'd like to add something that creates user, user, until EOF '''
  file.close ()
  </code></pre>
