jupyterlab_scenes

Define subsets of code cells as scenes and execute them.

Usage

• The command "Toggle Scene Cell" attaches a cell to the active scene (or removes it again). Scene membership is indicated by the purple dot at the right end of the cell.
• The active scene is the scene that is currently displayed (purple dots) and can be edited.
• All cells of a scene are executed by clicking the run button in the scene.
• One cell can be part of multiple scenes.

• By clicking the init button, one scene can be chosen to be automatically executed as the kernel becomes ready (due to a restart or at the initial loading of the notebook).
• If a notebook with an already running kernel is opened, the init scene is not executed.
• Only one scene can be an init scene.

• To run a scene named My Favourite Scene programatically, do

  from ipylab import JupyterFrontEnd
  JupyterFrontEnd().commands.execute('scenes:run-scene', 'My Favourite Scene')
  

  But you may run only one scene at a time. No excessive looping as the scenes are executed only after the cell that launches the run-scene command is finished.
