Remove xticks in a matplotlib plot?

I have a semilogx plot and I would like to remove the xticks. I tried:

plt.gca().set_xticks([])
plt.xticks([])
ax.set_xticks([])

The grid disappears (ok), but small ticks (at the place of the main ticks) remain. How to remove them?

The plt.tick_params method is very useful for stuff like this. This code turns off major and minor ticks and removes the labels from the x-axis.

Note that there is also ax.tick_params for matplotlib.axes.Axes objects.

from matplotlib import pyplot as plt
plt.plot(range(10))
plt.tick_params(
    axis='x',          # changes apply to the x-axis
    which='both',      # both major and minor ticks are affected
    bottom=False,      # ticks along the bottom edge are off
    top=False,         # ticks along the top edge are off
    labelbottom=False) # labels along the bottom edge are off
plt.show()
plt.savefig('plot')
plt.clf()

Not exactly what the OP was asking for, but a simple way to disable all axes lines, ticks and labels is to simply call:

plt.axis('off')

Alternatively, you can pass an empty tick position and label as

# for matplotlib.pyplot

plt.xticks([], [])
# for axis object

ax.set_xticks([])
# for minor ticks
ax.set_xticks([], minor=True)
