SQLite with Python's sqlite3 Module
Creating databases, tables, INSERT/SELECT/UPDATE, parameterized queries, connection management.
Why Databases for AI?
Flat files work until your data grows or many parts of a project need the same records. A database gives you fast queries, structured schemas, and safe concurrent access.
SQLite is a zero-setup file-based database built into Python via the sqlite3 module — perfect for AI experiments and small projects.
Connecting with sqlite3.connect
sqlite3.connect opens (or creates) a database file and returns a connection. Use :memory: for a temporary in-RAM database.
import sqlite3
conn = sqlite3.connect("ml.db") # creates ml.db if missing
print(conn)All lessons in this course
