Python 2.7 has been EOL since January 2020. Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8. Debian oldoldstable (Buster, from 2019) has Python 3.7. RHEL 8 (from 2019) has Python 3.6. It's easier than ever to install a modern Python using uv. Given this, it seems like a fine idea to drop Python 2.7 support. Even though the build is not tested on Python as old as 3.3, I left comments stating that "3.3+" is the baseline Python version. However, it might make sense to bump this to e.g., 3.10, the oldest Python 3 version used during CI. Or, using uv or another method actually test on the oldest Python interpreter that is desirable to support (uv goes back to Python 3.7 easily; in October 2025, the oldest supported Python interpreter version will be 3.10) Signed-off-by: Jeff Epler <jepler@gmail.com>

Summary
Python 2.7 has been EOL since January 2020.
It's easier than ever to install a modern Python using uv.
Given this, it seems like a fine idea to drop Python 2.7 support.
I don't really expect this to be merged right away; perhaps when development officially shifts to Micropython2.
Testing
Relying on the CI to test this, but there's really not much code change here.

Even though the build is not tested on Python as old as 3.3, I left comments stating that "3.3+" is the baseline Python version. However, it might make sense to bump this to e.g., 3.10, the oldest Python 3 version used during CI.
