title: How do I append a blank value to a Python list?
body: <p>I'm trying to append a blank value to a Python list. Another value will eventually be added after that blank value as well.</p>
  
  <p>This works:</p>
  
  <pre><code>foo=['NYC', 'Ny', 'Us']
  print foo 
  #['NYC', 'Ny', 'Us']
  
  foo.append('')
  print foo 
  #['NYC', 'Ny', 'Us','']
  
  foo.append('TRUE')
  print foo
  #['NYC', 'Ny', 'Us','', 'TRUE']
  </code></pre>
  
  <p>As you can see, all the values are essentially strings. </p>
  
  <p>How do I make the first append a blank value without the quotes? I would rather have nothing if it's empty since I'll be passing this list eventually into a file and into a database.</p>
