title: How to correctly write a raw multiline string in Python?
body: <ol>
  <li>I know that you can create a multi-line string a few ways:</li>
  </ol>
  
  <p><strong>Triple Quotes</strong></p>
  
  <pre><code>'''
  This is a 
  multi-line
  string.
  '''
  </code></pre>
  
  <p><strong>Concatenating</strong></p>
  
  <pre><code>('this is '
  'a string')
  </code></pre>
  
  <p><strong>Escaping</strong></p>
  
  <pre><code>'This is'\
  'a string'
  </code></pre>
  
  <ol start="2">
  <li><p>I also know that prefixing the string with <code>r</code> will make it a raw string, useful for filepaths.</p>
  
  <pre><code>r'C:\Path\To\File'
  </code></pre></li>
  </ol>
  
  <p>However, I have a long filepath that both spans multiple lines and needs to be a raw string. How do I do this?</p>
  
  <p>This works:</p>
  
  <pre><code>In [1]: (r'a\b'
     ...: '\c\d')
  Out[1]: 'a\\b\\c\\d'
  </code></pre>
  
  <p>But for some reason, this doesn't:</p>
  
  <pre><code>In [4]:  (r'on\e'
     ...: '\tw\o')
  Out[4]: 'on\\e\tw\\o'
  </code></pre>
  
  <p>Why does the <code>"t"</code> only have one backslash?</p>
