Set default y-axis tick labels on the right

We can use rcParams["ytick.labelright"] (default: False), rcParams["ytick.right"] (default: False), rcParams["ytick.labelleft"] (default: True), and rcParams["ytick.left"] (default: True) to control where on the axes ticks and their labels appear. These properties can also be set in .matplotlib/matplotlibrc.

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams['ytick.right'] = plt.rcParams['ytick.labelright'] = True
plt.rcParams['ytick.left'] = plt.rcParams['ytick.labelleft'] = False

x = np.arange(10)

fig, (ax0, ax1) = plt.subplots(2, 1, sharex=True, figsize=(6, 6))

ax0.plot(x)
ax0.yaxis.tick_left()

# use default parameter in rcParams, not calling tick_right()
ax1.plot(x)

plt.show()
