Throughout the development of Python projects, incorporating third-party packages becomes essential. The conventional approach for managing project dependencies involves using a requirements.txt file. However, it’s easy to overlook updating this file with newly installed packages using pip freeze > requirements.txt. Moreover, it can be challenging to tell which dependencies were installed directly or indirectly via requirements.txt, making it unclear which packages are genuinely essential after removing some.

To address these issues, it’s recommended to adopt a modern package manager like poetry for more efficient project dependency management.
