Additional Challenges •  Add more than three moods. •  Add variables and logic so that the

program will automatically adapt to each person’s temperature range.

•  Store the temperatures values and the time to list variables. Display a plot of time vs. temperature after the For loop is done.

•  Replace the For loop with a While loop and use getKey with the CLEAR key to exit the loop.

Note: Experiment with temperature values to determine relevant temperature ranges for each person.
