title: Python "best formatting practice" for lists, dictionary, etc
body: <p>I have been looking over the <a href="https://en.wikipedia.org/wiki/Python_%28programming_language%29" rel="noreferrer">Python</a> documentation for code formatting best practice for large lists and dictionaries, for example,</p>
  
  <pre><code>something = {'foo' : 'bar', 'foo2' : 'bar2', 'foo3' : 'bar3'..... 200 chars wide, etc..}
  </code></pre>
  
  <p>or</p>
  
  <pre><code>something = {'foo' : 'bar',
               'foo2' : 'bar2',
               'foo3' : 'bar3',
               ...
               }
  </code></pre>
  
  <p>or</p>
  
  <pre><code>something = {
               'foo' : 'bar',
               'foo2' : 'bar2',
               'foo3' : 'bar3',
               ...
               }
  </code></pre>
  
  <p>How do I handle deep nesting of lists/dictionaries?</p>
