Using PostgreSQL Functions in Real Projects with Python
In this video, we explore how to use PostgreSQL functions in a real-world scenario and how to call those functions directly from Python. We start by creating a simple products table, then write a PostgreSQL function that uses a SELECT query to calculate discounted prices.
After testing the function inside PostgreSQL, we switch to Python and learn how to connect to a PostgreSQL database using psycopg2. You’ll see how easy it is to call a database function from Python and work with the returned results in your application.
