title: List of common docstring :types for pycharm
body: <p>Pycharm has a nice feature, whereby it reads the type declaration within a function docstring and does correct-usage checks where that function is used.</p>
  
  <p>Is there a nice resource, that lists rules and names for all commonly used types?</p>
  
  <p><strong>Note:</strong><br>
  I have provided an answer below, with everything that I have been able to figure out. Its far from comprehensive, though.</p>
