Python

Modern Python tooling (For example such as Flit and Hatch  ) support reproducible builds for pure-Python projectprojects. You can read more about reproducible build support in Flit reproducible build docs and Hatch reproducible build docs. It's a bit more complex if your assets require native compilation, but If if you can assure that your native compilation produces reproducible libraries on it's its own the packaging tool will produce reproducible builds..

Few A few guidelines:

• You should be following the modern ways of packaging projects - ideally define your project's metadata in pyproject.toml (PEP-621) and specify your build requirements as pinned dependencies following PEP-518
• In order to get plausible looking packages where files have "real" modification dates, you shoud should - in your build process - set SOURCE_DATE_EPOCH environment variable before running hatch build  or flit build - it should be a fixed timestamp
• It is recommended that you store your timestamp in the repository and update it whenever relase release is being prepared (so for example when release notes change). Example how it is stored (in yaml file) and updated automatically (with pre-commit) in Airflow
