Mastering SQLite in Python: The Ultimate Guide to Embedded Databases

Overview

Common Use Cases

• Developing mobile applications with a lightweight database
• Creating scalable solutions for embedded systems
• Prototyping and testing with a self-contained, serverless database

Code Examples

import sqlite3\n# Connect to a database (or create one if it doesn't exist)\nconn = sqlite3.connect('example.db')\n# Create a cursor object using the cursor() method\ncursor = conn.cursor()\n# Create a table\ncursor.execute('''CREATE TABLE IF NOT EXISTS students (id INTEGER PRIMARY KEY, name TEXT, grade REAL)''')\n# Insert a record\ncursor.execute("INSERT INTO students (name, grade) VALUES ('Alice', 85.5)")\n# Commit the changes\nconn.commit()\n# Close the connection\nconn.close()

# Function to fetch all records\ndef fetch_all_records():\n    conn = sqlite3.connect('example.db')\n    cursor = conn.cursor()\n    cursor.execute('SELECT * FROM students')\n    results = cursor.fetchall()\n    conn.close()\n    return results\n# Fetch and print records\nrecords = fetch_all_records()\nfor record in records:\n    print(record)
