title: what is the difference between .ipython vs .ipynb?
body: <p>I know that .py is a regular python file. Also, .ipynb is a python notebook that contains the notebook code, and IPython is supposed to be an interactive shell for Python.</p>
  <p>But when I want to write a Jupiter notebook code and run it in VSC, what extension should I use for my code file? .ipython or .ipynb?</p>
