Without looking at the example, describe what changes when you modify one input in Plotting with matplotlib. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Describe what changing the second list of numbers would do to the plot.
