If the index is a MultiIndex (hierarchical), level(s) to set (None for all levels). Otherwise level must be None

if True, mutates in place

Examples
>>> Index([1, 2, 3, 4]).set_names('foo') Int64Index([1, 2, 3, 4], dtype='int64') >>> Index([1, 2, 3, 4]).set_names(['foo']) Int64Index([1, 2, 3, 4], dtype='int64') >>> idx = MultiIndex.from_tuples([(1, u'one'), (1, u'two'), (2, u'one'), (2, u'two')], names=['foo', 'bar']) >>> idx.set_names(['baz', 'quz']) MultiIndex(levels=[[1, 2], [u'one', u'two']], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'baz', u'quz']) >>> idx.set_names('baz', level=0) MultiIndex(levels=[[1, 2], [u'one', u'two']], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'baz', u'bar'])
