title: Set breakpoint in imported python module in vs code
body: <p>I am trying to set a breakpoint in an external Python module in VS code.</p>
  
  <p>I have tried editing the source file and inserting <code>import pdb; pdb.set_trace()</code> where I want the breakpoint.</p>
  
  <p>This enters the pdb command line debugger rather than the debugger in the VS Code GUI.</p>
  
  <p>How do I set a breakpoint in an imported Python module so that I enter the VS Code debugger?</p>
