Hide axis values but keep axis tick labels in matplotlib

Question

I have this image:

plt.plot(sim_1[\'t\'],sim_1[\'V\'],\'k\')
plt.ylabel(\'V\')
plt.xlabel(\'t\')
plt.show()

I want to hide the numbers

Answer 1

This works great. Just paste this before plt.show():

plt.gca().axes.get_yaxis().set_visible(False)

Boom.
