X,Y = np.meshgrid(xlist, ylist) # Create 2-D grid xlist,ylist values Z = np.sqrt(X**2 + Y**2) # Compute function values on the grid We also need to specify the contour levels (of Z) to plot. You can either specify a positive integer for the number of automatically- decided contours to plot, or you can give a list of contour (function) values in the
