Set Up Python Environment: Install Python from the official website. Verify installation by running python --version in your terminal or command prompt.

Install Required Libraries: For SQLite (built-in): No installation needed. For MySQL: Run pip install mysql-connector-python. For PostgreSQL: Run pip install psycopg2. For ORM tools like SQLAlchemy: Run pip install sqlalchemy.

Connect to the Database: For SQLite: Use sqlite3.connect('database_name.db'). For MySQL: Use mysql.connector.connect(host='hostname', user='username', password='password', database='db_name'). For PostgreSQL: Use psycopg2.connect(database='db_name', user='username', password='password', host='hostname', port='port_number').

Create a Cursor Object: Use cursor = connection.cursor() to execute SQL commands.

Execute SQL Queries: Use cursor.execute('SQL_QUERY') for operations like creating tables, inserting, updating, or deleting data.

Commit Changes: For operations that modify the database, use connection.commit() to save changes.

Fetch Data: Use cursor.fetchall() or cursor.fetchone() to retrieve query results.

Close the Connection: Always close the connection using connection.close() to free resources.

Optional: Use ORM Tools: For a more Pythonic approach, use SQLAlchemy or Django ORM to interact with databases using Python objects and classes.
