title: Visual Studio Code Python debugging "Exception has occurred SystemExit"
body: <p>I've been using Visual Studio code for a long time with the Python extension.</p>
  
  <p>Currently I have Visual Studio Code version 1.27.2, Python extension "ms-python.python" version 2018.8.0, python version 3.6.6, hosted by a Windows 10 1803 Enterprise Edition system.</p>
  
  <p>Compared to the past, the latest version of Code / MS Python behaves differently in the debugging process.</p>
  
  <p>In the past the execution of the following Python code, within Visual Studio Code, would not have generated any exceptions:</p>
  
  <pre><code># Import exit from sys
  from sys import exit as sys_exit
  # Exit to system with errorlevel set to 1
  sys_exit(1)
  # Next instruction is never executed.
  # Executing the script directly from the terminal in Windows sets the
  # errorlevel to 1 and the script execution is terminated. 
  print('unreachable code')
  </code></pre>
  
  <p>Now the result is a SystemExit exception when sys_exit(1) instruction is executed (<a href="https://i.stack.imgur.com/LMgYO.png" rel="noreferrer">VSCode screenshot</a>).</p>
  
  <p>Question: is there a way to disable this behavior and return to the previous one?</p>
