I think the marginal gain would be a lot less for Jupyter notebooks, but I've definitely rerun individual cells and wasted time there before.

I think it could help if you forget to save the output of a function within a single cell like this:

1. print(f(x)) # -> check what happened 2. out = f(x) # -> turns out we want to save this, so we have to wait again
