title: Create .pyi files automatically?
body: <p>How can I automatically create the boilerplate code of <a href="https://www.python.org/dev/peps/pep-0484/#stub-files" rel="noreferrer">pyi</a> files?</p>
  
  <p>I want to create a <a href="https://www.python.org/dev/peps/pep-0484/#stub-files" rel="noreferrer">pyi</a> file for type hinting as described in <a href="https://www.python.org/dev/peps/pep-0484/" rel="noreferrer">pep484</a> which contains all method names.</p>
  
  <p>I don't want magic. I want to add the type information after auto creating the file. </p>
  
  <p>I want to avoid the copy+paste work.</p>
  
  <p>Goal: Type hinting in PyCharm for Python2.</p>
