How to retrieve SQL result column value using column name in Python using MySql data base?

Question

Is there a way to retrieve SQL result column value using column name instead of column index in Python?

result = `select name, deptname from employee;`

I tried below one:

cursor = conn.cursor(MySQLdb.cursors.DictCursor)
cursor.execute("SELECT name, category FROM animal")
result_set = cursor.fetchall()
for row in result_set:
    print "%s, %s" % (row["name"], row["deptname"])

Here I got an error like:

TypeError: tuple indices must be integers, not str

Any help will be awesome?

Actually you are getting what you wanted. You just need to use the row not as a dictionary but as a tuple. That means that the indices are numbers, not strings. Try

print "%s, %s" % (row[0], row[1])

instead

Yeah, but the OP specifically asks Is there a way to retrieve SQL result column value using column name instead of column index in Python?..meaning the OP actually wants dictionary access to the table rows.

You are not correctly specifying that you need a dictionary cursor. Do that when you call the connect() method, set the cursorclass:

import MySQLdb

conn = MySQLdb.connect(user='user', 
                       passwd='password', 
                       db='db_name', 
                       cursorclass=MySQLdb.cursors.DictCursor) 
cursor = conn.cursor()
