Examples
>>> idx = MultiIndex.from_tuples([(1, u'one'), (1, u'two'), (2, u'one'), (2, u'two')], names=['foo', 'bar']) >>> idx.set_levels([['a','b'], [1,2]]) MultiIndex(levels=[[u'a', u'b'], [1, 2]], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'foo', u'bar']) >>> idx.set_levels(['a','b'], level=0) MultiIndex(levels=[[u'a', u'b'], [u'one', u'two']], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'foo', u'bar']) >>> idx.set_levels(['a','b'], level='bar') MultiIndex(levels=[[1, 2], [u'a', u'b']], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'foo', u'bar']) >>> idx.set_levels([['a','b'], [1,2]], level=[0,1]) MultiIndex(levels=[[u'a', u'b'], [1, 2]], labels=[[0, 0, 1, 1], [0, 1, 0, 1]], names=[u'foo', u'bar'])
