TypeError: tuple indices must be integers, not str

Question

I am trying to pull data from a database and assign them to different lists. This specific error is giving me a lot of trouble \"TypeError: tuple indices must be integers, not s

Answer 1

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.
