The connection object has a useful \u2018row_\u00a3actory\u2019 property with which row in the result set can be converted into some meaningful representation. This can be done either by assigning a row factory to a user-defined function that will return a custom object or by setting it to the constructor of the Row class.<\/p>\n
Row class has been defined in the sqlite3 module, whose primary purpose is to be used as a row factory. As a result, the row of the result set is returned as a Row object. Row class defines a keys () method that returns column names used in the SELECT statement. Values are accessible using the index as well as by name.<\/p>\n
