title: How do I list the current line in python PDB?
body: <p>In the perl debugger, if you repeatedly list segments of code taking you away from the current line, you can return to the current line by entering the command <code>.</code> (dot).   </p>
  
  <p>I have not been able to find anything comparable using the python PDB module.  If I <em>list</em> myself away from the current line and want to view it again, it seems I have to either remember the line number that was currently executing (unlikely for me) or execute a statement (often undesirable).  </p>
  
  <p>Am I missing something?</p>
