Colormaps
When you want to differentiate regions, but not imply any type of relationship between the regions, a qualitative colormap is the best choice.
In this exercise you'll compare a qualitative colormap to a sequential (quantitative) colormap using the school districts GeoDataFrame, which is available for you as school_districts.

# Set legend style
lgnd_kwds = {'title': 'School Districts',
'loc': 'upper left', 'bbox_to_anchor': (1, 1.03), 'ncol': 1}
# Plot the school districts using the tab20 colormap (qualitative)
school_districts.plot(column = ____, ____ = 'tab20', ____ = True, ____ = lgnd_kwds)
plt.xlabel('Longitude')
plt.ylabel('Latitude')
plt.title('Nashville School Districts')
plt.show();
