Great job on implementing the core functionalities and meeting the task requirements! 🎉 While there are a few areas for improvement, such as refining error handling and ensuring compatibility with earlier Python versions, these are minor and don't impact the overall functionality. Keep up the good work and consider the feedback for future enhancements! 😊

The create_objects function assumes that all elements in the data list are unique. If there are duplicates, this could lead to integrity errors when adding to the database. Consider adding a check to handle duplicates or ensure that the input data is pre-validated.

The error handling in the create_movie function is quite generic. Catching SQLAlchemyError will handle all SQLAlchemy-related exceptions, but it might be beneficial to differentiate between different types of errors (e.g., integrity errors, connection errors) to provide more specific feedback to the user.

The patch_movie function incorrectly uses HTTPException to return a success message. Instead, it should return a dictionary or a response object with the appropriate status code and message. HTTPException is intended for error handling.

The use of the pipe operator | for type hinting (e.g., str | None) is only supported in Python 3.10 and later. If you need to maintain compatibility with earlier versions of Python, consider using Optional[str] instead.
