Like the error says  row is a tuple  so you can t do row  pool number    You need to use the index  row 0

I think you should do   for index  row in result     If you wanna access by name

Just adding a parameter like the below worked for me  cursor conn cursor dictionary True   I hope this would be helpful either

The Problem is how you access row   Specifically row  waocs   and row  pool number   of ocs row  pool number    int row  waocs     If you look up the official-documentation of fetchall   you find      The method fetches all  or all remaining  rows of a query result set and returns a list of tuples    Therefore you have to access the values of rows with row   integer    like row 0

SQlite3 has a method named row factory  This method would allow you to access the values by column name  https   www kite com python examples 3884 sqlite3-use-a-row-factory-to-access-values-by-column-name

TL DR  add the parameter cursorclass MySQLdb cursors DictCursor at the end of your MySQLdb connect     I had a working code and the DB moved  I had to change the host user pass  After this change  my code stopped working and I started getting this error  Upon closer inspection  I copy-pasted the connection string on a place that had an extra directive  The old code read like    conn   MySQLdb connect host  oldhost                           user  olduser                           passwd  oldpass                           db  olddb                            cursorclass MySQLdb cursors DictCursor    Which was replaced by    conn   MySQLdb connect host  newhost                           user  newuser                           passwd  newpass                           db  newdb     The parameter cursorclass MySQLdb cursors DictCursor at the end was making python allow me to access the rows using the column names as index  But the poor copy-paste eliminated that  yielding the error   So  as an alternative to the solutions already presented  you can also add this parameter and access the rows in the way you originally wanted      I hope this helps others
