Hey folks, The macOS 12.3 seed remove Python 2. Most of WebKit’s tools are already Python 3 compatible, and in the last few weeks, we changed a number of buildbot invocation and shebangs so that workflows critical to the project are Python 3 by default. There are still a number of scripts which are Python 2 by default, though. Bellow, all of those scripts are listed. If a script important to your workflow is listed, now is a good time to help the project out by converting that script to Python 3.
