xorbits.pandas.DataFrame.lookup#

DataFrame.lookup(row_labels: Sequence[Union[Hashable, Sequence[Hashable]]], col_labels: Sequence[Union[Hashable, Sequence[Hashable]]]) → numpy.ndarray[source]#

Label-based “fancy indexing” function for DataFrame.

Deprecated since version 1.2.0: DataFrame.lookup is deprecated, use pandas.factorize and NumPy indexing instead. For further details see Looking up values by index/column labels.

Given equal-length arrays of row and column labels, return an array of the values corresponding to each (row, col) pair.

Parameters

  • row_labels (sequence) – The row labels to use for lookup.

  • col_labels (sequence) – The column labels to use for lookup.

Returns

The found values.
