MySQL Get Started

This lesson is part of Python · All levels

Summary

This lesson introduces how to connect Python to a MySQL database using the mysql-connector-python module. You'll learn to make connections, create cursors, execute queries, take results, and then close the connection neatly. A properly closed connection prevents a resource leak on a database server.

Key points

Install the driver with the pip install mysql-connector-python and then import mysql.connector.
It accepts host, user, password, and database parameters.
Cursors are created from a connection with conn.cursor() and serve as a query execution object.
The SELECT query is taken with fetchone() or fetchall(), while the INSERT/UPDATE/DELETE query needs conn.commit().
Always close the connection using conn.close() or use context manager try-finally.
