5. Working with Different Database Types

   A. SQLite

      - Introduction to SQLite and its usage in Python

SQLite is a lightweight, self-contained relational database management system (RDBMS) that is embedded into the application. It doesn't require a separate server process and allows you to directly interact with the database using SQL queries. In Python, you can use the built-in `sqlite3` module to work with SQLite databases. 

Here's a brief overview of how to use SQLite in Python:

1. **Connect to a Database**: Use the `connect()` function from the `sqlite3` module to connect to an SQLite database file. If the file doesn't exist, SQLite will create it.

import sqlite3

# Connect to database (creates if it doesn't exist)

conn = sqlite3.connect('example.db')

2. **Create a Cursor**: After connecting, create a cursor object using the `cursor()` method. The cursor is used to execute SQL commands.

# Create a cursor object

cursor = conn.cursor()

3. **Execute SQL Commands**: You can execute SQL commands using the `execute()` method of the cursor.

# Execute a SQL command to create a table

cursor.execute('''CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)''')

4. **Commit Changes**: After executing SQL commands that modify the database (e.g., INSERT, UPDATE, DELETE), make sure to commit the changes using the `commit()` method of the connection object.

# Commit changes

conn.commit()

5. **Query Data**: Use the `execute()` method to query data from the database.

# Execute a SELECT query

cursor.execute("SELECT * FROM users")

# Fetch the results

rows = cursor.fetchall()

# Process the results

for row in rows:

    print(row)

6. **Close Connection**: Always close the connection when you're done working with the database.

# Close connection

conn.close()

This is a basic overview of using SQLite in Python. You can perform a wide range of operations, including creating, querying, updating, and deleting data from tables.

   B. MySQL

• Overview of MySQL database integration with Python  

Integrating MySQL with Python allows you to interact with MySQL databases using Python code. Here's an overview of how to integrate MySQL with Python:

1. **Install MySQL Connector/Python**: First, you need to install the MySQL Connector/Python package, which provides an interface for Python to interact with MySQL databases. You can install it using pip:

pip install mysql-connector-python

2. **Connect to MySQL Database**: After installing the MySQL Connector/Python package, you can connect to a MySQL database using the `connect()` function provided by the package. You'll need to provide the database host, username, password, and database name.

import mysql.connector

# Connect to MySQL database

conn = mysql.connector.connect(

    host="localhost",

    user="username",

    password="password",

    database="database_name"

3. **Create a Cursor**: Similar to SQLite, you need to create a cursor object to execute SQL commands.

# Create a cursor object

cursor = conn.cursor()

4. **Execute SQL Commands**: You can execute SQL commands using the `execute()` method of the cursor.

# Execute a SQL command to create a table

cursor.execute('''CREATE TABLE IF NOT EXISTS users (id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), age INT)''')
