I am just watching James Powell giving a talk (https://www.youtube.com/watch?v=DlgbPLvBs30) and using (I think) to execute only the code he highlights at the moment.
I tried several things and searches but find out how could do the same with Sublime 3? (almost like a Jupyter notebook)
The only unsatisfactory workaround I have is to comment the parts I don't want to exec.
How I can do this? For sure, there must be a way...
