How to Iterate through cur.fetchall() in Python

Question

I am working on database connectivity in Python 3.4. There are two columns in my database.

Below is the query which gives me all the data from two columns in shown f

Answer 1

As the output you given [('F:\\test1.py', '12345abc'), ('F:\\test2.py', 'avcr123')]

for i, row in data:
    print(i)  # i is column1's value
    print(row)# row is column's value

So you don't need row[i] or row[j], that was wrong, in that each step of that iteration

for i, row in data 

is the same as i, row = ('abc', 'def') it set abc to variable i and 'def' to row

BTW ,I don't know what database you use, if you use Mysql and python driverMySQL Connector, you can checkout this guide to fetch mysql result as dictionary you can get a dict in iteration, and the keys is your table fields' name. I think this method is convenient more.
