Use typing.Self and drop typing_extensions in automatic_differentiation by priya-sundaram-dev · Pull Request #15114 · TheAlgorithms/Python

priya-sundaram-dev · 2026-08-28T22:58:12Z

Re-opening the automatic_differentiation.py change from #15113 as its own PR (no uv.lock), per @cclauss's request.

machine_learning/automatic_differentiation.py was the only module importing Self from typing_extensions, behind a # noqa: UP035. Since the repo requires Python >=3.14, typing.Self (added in 3.11) is always available — so it now imports from the stdlib and the noqa is removed (UP035 stays enforced). Verified: 13 doctests pass, ruff check clean.

Describe your change:

Add an algorithm?
Fix a bug or typo in an existing algorithm?
Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request.
Documentation change?

Checklist:

`machine_learning/automatic_differentiation.py` was the only module importing `Self` from `typing_extensions`, behind a `# noqa: UP035`. Since the repo requires Python >=3.14, `typing.Self` (added in 3.11) is always available, so import it from the stdlib and drop the noqa. ### Describe your change: * [x] Add an algorithm? * [ ] Fix a bug or typo in an existing algorithm? * [ ] Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request. * [ ] Documentation change? ### Checklist: * [x] I have read [CONTRIBUTING.md](https://github.com/TheAlgorithms/Python/blob/master/CONTRIBUTING.md). * [x] This pull request is all my own work -- I have not plagiarized. * [x] I know that pull requests will not be merged if they fail the automated tests. * [x] This PR only changes one algorithm file.
