Clarification needed for python environment usage

[mianasbat]

I am following the python notes for working as instructor in the next carpentry workshop. The setup section gives a nice detail of getting data and code. It also describe various ways of running the python code for the exercise.

While the jupyter notebook is kind of preferred and easy to use its not mentioned anywhere how to run the code in jupyter notebook. May be small detail of how to execute the code e.g. alt + enter to run the current cell, cmd + enter to run multiple cells.
