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

Question

I\'d like to NOT specify a color for each plotted line, and have each line get a distinct color. But if I run:

from matplotlib import pyplot as plt
for i in

You can use a predefined "qualitative colormap" like this:

from matplotlib.cm import get_cmap

name = "Accent"
cmap = get_cmap(name)  # type: matplotlib.colors.ListedColormap
colors = cmap.colors  # type: list
axes.set_prop_cycle(color=colors)

Tested on matplotlib 3.0.3. See https://github.com/matplotlib/matplotlib/issues/10840 for discussion on why you can't call axes.set_prop_cycle(color=cmap).

A list of predefined qualititative colormaps is available at https://matplotlib.org/gallery/color/colormap_reference.html :
