Formatting the font of ticklabels in matplotlib

I have a font dictionary with which I would like to format the ticklabels in a matplotlib plot.

The Axes.set_xticklabels() function comes with a warning that the method should only be used after fixing the tick positions using Axes.set_xticks. To set the ticks, I need to give them positions. I want to use the default positions and numerical formatting provided by matplotlib, and only specify the way in which the text is to be formatted.

How can I do this?

My initial attempt

ax.set_xticklabels(ax.get_xticks(), fontdict=mydict)

works, vis a vis the font formatting, but the ticklabels don't change on zooming, and the numerical formatting changed (eg originally 10, afterwards 10.0)

The easiest way is to use pyplot xticks with no ticks or labels:

import matplotlib.pyplot as plt

mydict = {'fontweight': 'bold'}

fig, ax = plt.subplots()
plt.xticks(**mydict)

enter image description here

If you want to use the OOP interface, you can achieve the same by

for label in ax.get_xticklabels():
    label.update(mydict)
