pandas.MultiIndex.to_hierarchical — pandas 0.18.1 documentation (original) (raw)

Return a MultiIndex reshaped to conform to the shapes given by n_repeat and n_shuffle.

Useful to replicate and rearrange a MultiIndex for combination with another Index with n_repeat items.

idx = MultiIndex.from_tuples([(1, u'one'), (1, u'two'), (2, u'one'), (2, u'two')]) idx.to_hierarchical(3) MultiIndex(levels=[[1, 2], [u'one', u'two']], labels=[[0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1], [0, 0, 0, 1, 1, 1, 0, 0, 0, 1, 1, 1]])
