As the generated `parse.py` file is just Python code, you can modify it
and add breakpoints to debug or better understand some complex situations.

However, this does not work with the existing `Grammar/python.gram` file.
See [#133560](https://github.com/python/cpython/issues/133560)
and [#96424](https://github.com/python/cpython/issues/96424) for more information.
