Turn off the upper/right axis tick marks

Question

I want to make the ticks on the right and upper axis invisible and am not sure what the third line should be:

import matplotlib.pyplot as plt
plt.plot(X,Y)
#         


        

Answer 1

tick_params should do it.

I don't have matplotlib installed on my current computer, so I can't test it, but this should work:

import matplotlib.pyplot as plt

ax = plt.subplot(111)
plt.plot([0,1], [0,1])
ax.tick_params(labeltop='off', labelright='off')
plt.show()
