title: Can't Convert List of String into Binary
body: <p>I'm trying to convert a list for example mylist = ['apple', 'pineapple'] by using</p>
  
  <pre><code>[''.join(format(i, 'b') for i in bytearray(mylist, encoding ='utf-8'))]
  </code></pre>
  
  <p>but receive <strong>"encoding or errors without a string argument"</strong>. the expected result is to be </p>
  
  <pre><code>['11000011110000111000011011001100101', '111000011010011101110110010111000011110000111000011011001100101']
  </code></pre>
