The dict cursors allow to access to the retrieved records using an interface similar to the Python dictionaries instead of the tuples.
Add following code into your cursor function
cursor_factory=psycopg2.extras.RealDictCursor
After adding the above code your cursor should be look like this -
cur = con.cursor(cursor_factory=psycopg2.extras.RealDictCursor)
if you have an error of not found class .extra -
AttributeError: module 'psycopg2' has no attribute 'extras'
Resolved this error by importing class as below
Now if you run this code, you will get data in dictionary from redshift as key, value pair like below :-
{'id': 1234567, 'date': datetime.date(2019, 2, 13), 'hour': 0, 'code': 42107, 'count': 6, 'revenue': None, 'payout': None, 'week': 7}
Add following code into your cursor function
cursor_factory=psycopg2.extras.RealDictCursor
After adding the above code your cursor should be look like this -
cur = con.cursor(cursor_factory=psycopg2.extras.RealDictCursor)
if you have an error of not found class .extra -
AttributeError: module 'psycopg2' has no attribute 'extras'
Resolved this error by importing class as below
import psycopg2 import psycopg2.extras
Now if you run this code, you will get data in dictionary from redshift as key, value pair like below :-
{'id': 1234567, 'date': datetime.date(2019, 2, 13), 'hour': 0, 'code': 42107, 'count': 6, 'revenue': None, 'payout': None, 'week': 7}
