How do you make a rainbow plot in Python?

Steps

How do you pick a new color for each plotted line within a figure in matplotlib?

Basically you just do this: [colormap(i) for i in np. linspace(0, 0.9, num_plots)] , where colormap is one of the colormaps in matplotlib.pyplot.cm and numplots is the number of unique colors that you want.
