title: Defining more than one path in VS Code PYTHONPATH
body: <p>I cannot find a clear answer on how to define multiple paths for the PYTHONPATH variable. I have tried all possible combinations of different solutions posted on various sites, but none of them work. Why can't this be clearly documented somewhere?</p>
  
  <p>I tried every combination of separator and quoting:</p>
  
  <pre><code>"env": {"PYTHONPATH": "D:\\Users\\path\\a\\"; "D:\\Users\\path\\b\\"},
  "env": {"PYTHONPATH": "D:\\Users\\path\\a\\": "D:\\Users\\path\\b\\"},
  "env": {"PYTHONPATH": "D:\\Users\\path\\a\\; D:\\Users\\path\\b\\"},
  ...
  </code></pre>
