In matplotlib, how do you display an axis on both sides of the figure?

Question

I want to draw a plot with matplotlib with axis on both sides of the plot, similar to this plot (the color is irrelevant to this question):

How can I do this with matplotlib?

Note: contrary to what is shown in the example graph, I want the two axis to be exactly the same, and want to show only one graph. Adding the two axis is only to make reading the graph easier.

You can use tick_params() (this I did in Jupyter notebook):

import matplotlib.pyplot as plt  bar(range(10), range(10)) tick_params(labeltop=True, labelright=True) 

Generates this image:

UPD: added a simple example for subplots. You should use tick_params() with axis object.

This code sets to display only top labels for the top subplot and bottom labels for the bottom subplot (with corresponding ticks):

import matplotlib.pyplot as plt  f, axarr = plt.subplots(2)  axarr[0].bar(range(10), range(10)) axarr[0].tick_params(labelbottom=False, labeltop=True, labelleft=False, labelright=False,                      bottom=False, top=True, left=False, right=False)  axarr[1].bar(range(10), range(10, 0, -1)) axarr[1].tick_params(labelbottom=True, labeltop=False, labelleft=False, labelright=False,                      bottom=True, top=False, left=False, right=False) 

Looks like this:
