how to draw dendrogram in python

>>> hierarchy.set_link_color_palette(['m', 'c', 'y', 'k'])
>>> fig, axes = plt.subplots(1, 2, figsize=(8, 3))
>>> dn1 = hierarchy.dendrogram(Z, ax=axes[0], above_threshold_color='y',
...                            orientation='top')
>>> dn2 = hierarchy.dendrogram(Z, ax=axes[1],
...                            above_threshold_color='#bcbddc',
...                            orientation='right')
>>> hierarchy.set_link_color_palette(None)  # reset to default after use
>>> plt.show()
