Jupyter

• Dataquest.io has a very good tutorial on how to use Jupyter, the other interface besides Spyder for running Python code.

• 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).

• To put something into Markdown comment language instead of Python, switch the box at the top of the editor from Code to Markdown.

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

import os; os.chdir('c:\\Users\\erasmuse\\Downloads\\')

• You don't always have to use the print command to get the value of a new variable to show. This is interactive, a shell not batch. Sort of. Except you do have to keep Running cells.
