In this video, you’ll learn how to connect Python to PostgreSQL and load data into a pandas DataFrame.
This is the first step in building any machine learning or data science project.
🔹 How to connect Python to PostgreSQL using SQLAlchemy
🔹 How to write SQL queries inside Python
🔹 How to load data into a pandas DataFrame
🔹 How to inspect and understand your data
🔹 How data flows from database to ML pipeline
Technologies Used
Python
Pandas
SQLAlchemy
PostgreSQL
Code Explained
✔ Database connection using create_engine
✔ SQL query execution using pandas
✔ Data validation (empty check)
✔ Data inspection using head(), shape(), info(), describe()
Why This Matters
Before building any machine learning model, we need clean and structured data.
This step connects your database with your ML pipeline.
