how to use sqlite3 in python

Title: A Comprehensive Guide to Using SQLite3 in Python
Introduction:
SQLite is a lightweight, serverless, and self-contained database engine that is widely used in embedded systems and small to medium-sized applications. Python comes with a built-in module called sqlite3 that provides an easy and efficient way to interact with SQLite databases. In this tutorial, we will explore the basics of using SQLite3 in Python, covering database creation, table manipulation, data insertion, querying, and more.
Prerequisites:
Before we begin, make sure you have Python installed on your system. Additionally, there is no need to install any external libraries for SQLite, as it is included in the Python standard library.
Step 1: Import the sqlite3 Module
Step 2: Connect to a Database
To interact with an SQLite database, you need to establish a connection. If the database does not exist, it will be created.
Step 3: Create a Cursor Object
A cursor is used to execute SQL commands and navigate through the results.
Step 4: Create a Table
Let's create a simple table named 'users' with columns 'id', 'name', and 'age'.
Step 5: Insert Data
Insert data into the 'users' table.
Step 6: Query Data
Retrieve data from the 'users' table.
Step 7: Update and Delete Data
Update and delete data in the 'users' table.
Step 8: Commit and Close
After making changes, don't forget to commit and close the connection.
Conclusion:
Using the sqlite3 module in Python, you can easily create, manipulate, and query SQLite databases. This tutorial covers the basics, but SQLite and the sqlite3 module offer many more features and functionalities. Refer to the official documentation for more advanced usage and optimization techniques.
