The Arch Linux developers have announced that they have discontinued Python 2 packages from the project's repositories. The Python 2 branch was deprecated back in January 2020, but after that it took a long time to gradually rework packages tied to Python 2.
For users who require Python 2, the option to keep packages on the system is provided, but they will remain for security updates. For those who need Python 2 packages with fixes, it is recommended to use the AUR or unofficial repositories.
