How do I manage sessions in SQLAlchemy?

To manage sessions in SQLAlchemy, you typically use the sessionmaker class to create a session factory.

Can you show me an example of creating a session?

Sure! Here's a simple example:

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker

engine = create_engine('sqlite:///example.db')
Session = sessionmaker(bind=engine)
session = Session()

What should I do to commit changes to the database?

After making changes to your objects, you can commit them using session.commit(). Don't forget to handle exceptions!

How do I handle session rollback in case of an error?

You can use a try-except block. If an error occurs, call session.rollback() to revert the changes.
