Coding is a side benefit to the way we want to use Jupyter. It is not the primary reason that this is a useful tool. In most cases we are using jupyter's code cells (assumed to be running python) as calculators. Extensive use of the numpy library is used precisely so we can avoid having to 'loop' over elements and not have to learn the intricacies of data structures. That being said, some coding skill is helpful as we develop models for physical phenomenon. Knowing how to build functions and how conditional branching works helps make things go more smoothly. Keep in mind that the materials here are not presented as a 'coding' course. There are many excellent online resources for that. This is just a quick set of guides to help fill out the details of what we want to do.
