Split title of a figure in matplotlib into multiple lines

I get the correct alignment when I format the string this way:

import matplotlib.pylab as plt

fig = plt.figure()#num=0,figsize=(8.27, 11.69), dpi=300)
ax  = fig.add_subplot(2, 2, 1)
ax.set_title('Normalized occupied \n Neighbors')

plt.show()
