MultiIndex.to_hierarchical(n_repeat, n_shuffle=1)
[source] -
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.
Parameters: n_repeat : int
Number of times to repeat the labels on self
n_shuffle : int
Controls the reordering of the labels. If the result is going to be an inner level in a MultiIndex, n_shuffle will need to be greater than one. The size of each label must divisible by n_shuffle.
Returns: MultiIndex
Examples
>>> 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]])
