I usually deal with this by defining a cell with the actual contents of the class/module code so that I can just re-execute that cell any time I make changes to it. Then I simply copy/paste all the code back into the module.py file once I'm done tweaking it and playing with it. Thus for me Jupyter sort of operates as almost an IDE of sorts.
