How can transaction management be automated independently, without relying on built-in database or system tools?

Automating type checking in Python during CI/CD can be done using static type analyzers like mypy.

Main steps:

1. Add type annotations to your code (PEP 484).
2. In your CI configuration (e.g., GitHub Actions, GitLab CI, Jenkins), add a step to run mypy.
3. If mypy detects type errors, the build is considered failed.

Example command to run mypy:

mypy path/to/your/code

This allows for automatic verification of type correctness and helps prevent errors early in the development process.
