title: Not printing file contents
body: <p>I'm trying to read and print the contents of a text file, but nothing shows up:</p>
  <pre><code>coffee = open('coffeeInventory.txt' , 'r')
  coffee.seek(0)
  line = coffee.readline()
  while line != '':
      print(line)
      
  coffee.close()
  </code></pre>
  <p>Thank you for any advice.</p>
