What are the best practices for committing transactions in SQLAlchemy?

When committing transactions in SQLAlchemy, it's important to ensure that you handle sessions properly. Always use a context manager to manage your session lifecycle.

Can you explain what a context manager is in this context?

A context manager in Python is used to wrap the execution of a block of code. In SQLAlchemy, you can use it to automatically handle session commits and rollbacks.

What happens if I forget to commit or rollback?

If you forget to commit, your changes won't be saved to the database. If you forget to rollback after an error, it can leave your session in an inconsistent state.

Are there any specific methods I should use for committing?

Yes, you should use session.commit() to save changes and session.rollback() to revert changes in case of an error.
