Python SQLite: Database and Table Creation
This guide introduces the fundamentals of working with SQLite databases in Python, a widely used database technology conveniently built into Python installations. It walks through the process of creating a new database file and establishing a connection to it using the sqlite3 module. The core mechanism for interacting with the database is explained through the concept of a cursor, which acts as a pointer to execute commands. The source then details how to create tables within the database using SQL commands like CREATE TABLE, defining various data fields with specific types and constraints such as PRIMARY KEY, NOT NULL, and UNIQUE. Finally, it demonstrates how to insert data into these tables using INSERT INTO commands, emphasizing the importance of committing changes to the database and providing practical tips for viewing and managing the database using external software like DB Browser for SQLite.
