sqlite3 (1) – Programming in an object-oriented style

SQLite is a C library that provides a lightweight disk-based database that doesn’t require a separate server process and allows accessing the database using a nonstandard variant of the SQL query language. sqlite3 is a Python package that provides a SQL interface.

To program in an object-oriented style:

import sqlite3

class Database:
    def __init__(self,db):
        Connect to database or create a database if not exists.
        db: database file name.
        self.conn = sqlite3.connect(db)
        self.cursor = self.conn.cursor()

    def __del__(self):
        Close connection to database.

    def dbcommit(self):
        Write changes to database.

When an object is instantiated, it is connected to the database. db is the database file name, such as “stock_quotes.db”. If the file does not exist, a new database file will be created.
