title: getting started with python and postgresql - a w3schools tutorial
introduction:
postgresql is a powerful, open-source relational database management system, and python is a versatile programming language. combining the two allows developers to build robust and scalable applications. in this tutorial, we'll explore how to use python with postgresql, leveraging the popular online resource, w3schools, to guide us through the process.
prerequisites:
step 1: install required libraries
to interact with postgresql using python, we need to install the psycopg2 library. open your terminal or command prompt and run:
