More like an interactive calculation and graphing environment. 90% of the time, for me, the key output is a set of graphs. I like the consistency of plotting them programmatically in (matplotlib) code, while the interactive cell-based format makes it quick to run and make changes. Sure, it isn't too different to using an IDE, but the UI owes more to mathematical environments such as Maple and Mathematica.
