pandas.DataFrame.lookup

DataFrame.lookup(row_labels, col_labels)[source]

Label-based “fancy indexing” function for DataFrame. Given equal-length arrays of row and column labels, return an array of the values corresponding to each (row, col) pair.

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.

Parameters
row_labelssequence

The row labels to use for lookup.

col_labelssequence

The column labels to use for lookup.

Returns
numpy.ndarray

The found values.
