Pandas MultiIndex: What a two-level index looks like

What does a Python Pandas data frame’s multi-index look like?

This:

MultiIndex([(0.0, 1),
            (1.0, 1),
            (2.0, 1),
            (3.0, 1),
            (4.0, 1),
            (5.0, 1),
            (6.0, 1)],
           names=['passenger_count', 'VendorID'])
