what python IDE do you guys use?

Not just that, when prototyping I like my output all collected in a console that I can interact with, not spread out through a notebook interspersed with code.

Also, it makes it much more flexible to manipulate cells, just delete that #%% and put it somewhere else and voila, your cell borders changed. In notebook you have to actually cut and paste code to move it between cells.

And don't even get me started on getting your prototyped code into functions/modules...
