I use `#%%` code blocks in the interactive window for this purpose: https://code.visualstudio.com/docs/python/jupyter-support-py

This allows a normal editor workflow, interactive execution, and linear history of executed cells. But the code blocks can still be executed top-to-bottom and exported as a clean notebook for sharing purposes.
