[Python] Pyplot: Shared x-axis, how to shift individual ytick labels?

I would like to plot two datasets sharing the same x-axis, like so:

import numpy as np
import matplotlib.pyplot as plt

diagramm,axes=plt.subplots(nrows=2,sharex='col',gridspec_kw={'hspace': 0, 'wspace': 0})
axes[1].set_xlim([0,10])

axes[0].set_ylim(-1.0,1.0)
axes[1].set_ylim(-0.01,0.01)

xval=np.linspace(0,10,100)

axes[0].plot(xval,np.sin(xval), color="red")
axes[1].plot(xval,0.01*np.sin(xval), color="blue")

plt.show()


The result is the following:



You see the problem: The lowest/highest ytick labels of the upper/lower plot are overprinted on each other. How can I shift these labels up/down, so that they are both readable?

(Note: Obviously, I could add hspace or change the limits to, e.g., -1.1 and 0.011. However, I would prefer shifting the tick labels, if possible.)
