title: How to declare a long string in Python?
body: <p>I have a really long string in python:</p>
  
  <pre><code>long_string = '
  this is a really
  really
  really
  long
  string
  '
  </code></pre>
  
  <p>However, since the string spans multiple lines, python doesn't recognize this as a string. How do I fix this?</p>
