Announcing the Consortium for Python Data API Standards (via) Interesting effort to unify the fragmented DataFrame API ecosystem, where increasing numbers of libraries offer APIs inspired by Pandas that imitate each other but aren’t 100% compatible. The announcement includes some very clever code to support the effort: custom tooling to compare the existing APIs, and an ingenious GitHub Actions setup to run traces (via sys.settrace), derive type signatures and commit those generated signatures back to a repository.
