doc/source/whatsnew/vX.X.X.rstfile if fixing a bug or adding a new feature.Description of the change
read_csv()currently provides the description of an invalid row(expected_columns, actual_columns, number, text) when the row has too many elements whereengine="pyarrow", but the callable can only include the contents of the row whenengine="python".(For more details on pyarrow.csv.InvalidRow, see pyarrow documentation)
This PR proposes to additionally pass
expected_columns,actual_columnsandrowwhenon_bad_linesis a callable andengine="python", so that users can desribe the invalid row more in detail.The order of the arguments has been aligned with
pyarrow.
