Topical Guides
The pages here are intended for developers who are making or maintaining a package and want to follow modern best practices in Python.
New developers are encouraged to read the following pages. Veteran developers should still check out the tutorials, as it has a guide on recommendations for your CONTRIBUTING.md, and at least glance through other sections.
Following that, there are recommendations for style, intended to promote good practices and to ensure continuity across the packages. There is a dedicated page for static type checking with MyPy. There is then a guide on simple packaging, compiled packaging, or even classic packaging, which should help in ensuring a consistent developer and user experience when working with distribution.
A section on CI follows, with a general setup guide, and then two choices for using CI to distribute your package, on for pure Python, and one for compiled extensions. You can read about setting up good tests on the pytest page, with coverage. There’s also a page on setting up docs, as well.
New project template
Once you have completed the guidelines, there is a copier/cookiecutter/cruft project, scientific-python/cookie, that implements these guidelines and lets you setup a new package from a template in less than 60 seconds! Eleven build backends including compiled backends, generation tested in Nox, and kept in-sync with the guide.
Checking an existing project
We provide sp-repo-review, a set of repo-review checks for comparing your repository with the guidelines, runnable right in the guide via WebAssembly! All checks point to a linked badge in the guide.
