You can use a generator expression: all_matches = ( (r, c) for r, row in enumerate(table.rows) for c, cell in enumerate(row) if search_query.

You can use a generator expression: all_matches = ( (r, c) for r, row in enumerate(table.rows) for c, cell in enumerate(row) if search_query.matches(cell.value) ) found = next(all_matches, None) if found: logger.log("Found cell: {}".format(found)) return found It is lazy, so it stops as soon as the first match is found.
