TypeError: tuple indices must be integers, not str

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 str" I tried converting it to float and etc, but to no success.

The code goes as below

conn=MySQLdb.connect(*details*)
cursor=conn.cursor()
ocs={}
oltv={}
query="select pool_number, average_credit_score as waocs, average_original_ltv as waoltv from *tablename* where as_of_date= *date*"
cursor.execute(query)
result=cursor.fetchall()

for row in result:
    print(row)
    ocs[row["pool_number"]]=int(row["waocs"])
    oltv[row["pool_number"]]=int(row["waoltv"])

Sample output of print statement is as follows :

('MA3146', 711L, 81L)
('MA3147', 679L, 83L)
('MA3148', 668L, 86L)

And this is the exact error I am getting:

ocs[row["pool_number"]]=int(row["waocs"])
TypeError: tuple indices must be integers or slices, not str

How do I solve this error?

Solution

  • Like the error says, row is a tuple, so you can't do row["pool_number"]. You need to use the index: row[0].
