TypeError: tuple indices must be integers, not str
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.
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.
I know it is not specific to this question, but for anyone coming in from a Google search: this error is also caused by a comma behind an object that creates a tuple rather than a dictionary
>>>dict = {}
>>>tuple = {},
Tuple
>>>tuple_ = {'key' : 'value'},
>>>type(tuple_)
<class 'tuple'>
Dictionary
>>>dict_ = {'key' : 'value'}
>>>type(dict_)
<class 'dict'>
