New Features

• add enable/disable cell number in .py files (#1428), thanks to @dienhoa
  • When exporting a notebook to a .py file, we currently have something like # %% {nb_path} {cell_number} at the beginning of each exported cell.
  • This PR adds one new setting in the setting.ini: cell_number. When set to False, we disable the cell_number discussed above.
  • Side effect: The cell_number is used to update the changes from .py back to the notebook, so disabling it also disables this feature.

Bugs Squashed

• showdoc: SyntaxWarning: invalid escape sequence with Python 3.12 (#1396)
