Matplotlib colorbar ticks on left/opposite side

Question

One could generate a vertical colorbar like so(simplified):

import matplotlib.pyplot as plt
import matplotlib as mpl

plt.figure()
c_ax=plt.subplot(111)
cb =          


        

Answer 1

For some reason applying changes to the colorbar input axes (cax parameter) did not work for me.

However, grabbing the axes from the colorbar object and then applying the changes worked nicely:

cb.ax.xaxis.set_ticks_position("top")
