PostgreSQL Operations with Python

This repository contains a Python application that demonstrates how to perform basic CRUD (Create, Read, Update, Delete) operations on a PostgreSQL database using the psycopg2 library.

Requirements

  • Python 3.x
  • PostgreSQL Database
  • psycopg2 library (Install via pip install psycopg2)

Setup and Configuration

Before running the script, make sure you have a PostgreSQL database instance running. You will also need to configure the connection parameters in the code.

Connection Setup

The connection to the PostgreSQL database is established using the psycopg2 library. The connection parameters are as follows:

  • Host: localhost (or your PostgreSQL server)
  • Port: 5432 (default PostgreSQL port)
  • Database Name: postgres (or your specific database name)
  • User: postgres (or your PostgreSQL user)
  • Password: Your PostgreSQL user's password

Example:

host = "localhost"
port = 5432
dbname = "postgres"
user = "postgres"
password = "yourpassword"
