Allow accessing a TaskGroup's members via `[]` by Dev-iL · Pull Request #64430 · apache/airflow

Dev-iL · 2026-03-29T21:28:42Z

Minor feature (syntactic sugar): we can now do e.g. some_group["some_task"] to access the children of a task group regardless of the prefix_group_id setting.

Motivation: Discussion in AIR201's PR that made me aware that the shortest way to access child references is not that short - so I made it shorter and more natural (at least to me).

@uranusjr any objections?

uranusjr · 2026-04-20T08:34:21Z

This makes me wonder if we should also define __getitem__ on DAG, but that’s a different topic I guess. Feel free to open a new conversation on this.

The test asserts the feature works and fails on v3-2-test CI. Skip the test on the 3.2 line and link the tracking issue from both the test skip-reason and the disabled production-code site so the follow-up isn't lost.
