Answer 1

First of all, you have to install psycopg2 using pip :

pip install psycopg2

If you are on linux or Mac, you have to use sudo to give root permission.

After that, just import the library using:

import 'psycopg2'

If it doesn't work, you should to put the library folder in your project folder to work.
