 *Jupyter can be configured in Python to have a non-default home directory. Or, these Python commands are convenient:

 *[https://www.dataquest.io/blog/jupyter-notebook-tutorial/ Dataquest.io] has a very good tutorial on how to use Jupyter, the other interface besides Spyder for running Python code.

+*It looks like the main use of Jupyter is to save Python input and output in a convenient way.  A *.py file just has the input.  A Jupyter file runs in a browser window, but that doesn't seem to be important. Jupyter also divides the programs into cells, sections, so you can in Cells select "Run Cells and selection below" to run the current cell and move down to the next cell.
 *When I use Jupyter, search for Jupyter on my computer, launch it, and then do not shut off the black box that will appear along with the app itself (or it will stop working right).
