In this exercise, you will visualize a 2-D array repeatedly using both plt.contour() and plt.contourf(). You will use plt.subplot() to display several contour plots in a common figure, using the ...

So, here is a quick guide to contour plots and heatmaps - you can think of this as a guide for physicists. ... Try making V=X*Y and plotting that. Python can handle these array calculations.
