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          


        

Answer 1

I usually use the second one of these:

from matplotlib.pyplot import cm
import numpy as np

#variable n below should be number of curves to plot

#version 1:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
   plt.plot(x, y,c=c)

#or version 2:

color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
   c=next(color)
   plt.plot(x, y,c=c)

Example of 2:
