pandas.DataFrame.lookup

DataFrame.lookup(self, row_labels, col_labels) [source]

Parameters:
row_labels : sequence

The row labels to use for lookup

col_labels : sequence

The column labels to use for lookup

Returns:
numpy.ndarray

Notes

Akin to:

result = [df.get_value(row, col)
          for row, col in zip(row_labels, col_labels)]

Examples

values : ndarray
