Examples
>>> midx = ps.MultiIndex.from_arrays([['a', 'b'], [1, 2]], names = ['word', 'number']) >>> midx MultiIndex([('a', 1), ('b', 2)], names=['word', 'number'])
>>> midx.swaplevel(0, 1) MultiIndex([(1, 'a'), (2, 'b')], names=['number', 'word'])
>>> midx.swaplevel('number', 'word') MultiIndex([(1, 'a'), (2, 'b')], names=['number', 'word'])
