plt.show() does nothing… I tried in Chrome and Firefox, but in neither one does a plot appear although the instruction checkmark goes green as though everything worked.

What does the following code do?
y_upper = [i + (i*0.15) for i in viewers_hour]

I think there’s a bug in the browser. The code doesn’t actually do anything so nothing should print out. If you click to the next exercise it should show the plotting code in full.

#5

sets variable i to viewers_hour and does a mathematical function on it. Essentially with the plt.fill_between code draws in the shading around the line

#6

viewers_hour = [30, 17, 34, 29, 19, 14, 3, 2, 4, 9, 5, 48, 62, 58, 40, 51, 69, 55, 76, 81, 102, 120, 71, 63]

why the values are set in that order?
