Loading a Driver

• Before using the driver, perform the following operations:

  1. Decompress the driver package of the corresponding version and copy psycopg2 to the **site-packages **folder in the Python installation directory as the **root **user.

• Load a database driver before creating a database connection:

  import  psycopg2
