How can I change the font size of ticks of axes object in matplotlib [duplicate]

fig = plt.figure()
ax = fig.add_subplot(111)
plt.xticks([0.4,0.14,0.2,0.2], fontsize = 50) # work on current fig
plt.show()

the x/yticks has the same properties as matplotlib.text

Use:

subA.tick_params(labelsize=6)
