  <p>What is it? and how does it become my project path?</p>
  
  <p>in the last line of the screenshot, we can see the message <code>sys.path.extend([])</code> in the IPython console which indicates that it got my working dir successfully:</p>

  <p>This is the WORKING_DIR_AND_PYTHON_PATHS in the start script section in Pycharm Python console configuration which has a line of <code>sys.path.extend([WORKING_DIR_AND_PYTHON_PATHS])</code></p>
