`/usr/bin/python` invokes Python 2.7.18 on my just-bought Macbook Pro 14 running MacOS 12.2. Maybe that's because I installed the Xcode command line tools?
IIRC, Apple announced that Python 2 will be removed in a future version of macOS, without specifying a version. Looks like they removed it in macOS 12.3 [0].
