> I input python -h on the command line, and I can't find any -R option.

If you want to document it, the "usage" is in Python/initconfig.c. See also the -R option. My notes on adding a command line option:

> Victor, A sentence about hash randomization you wrote for #32329 in PR-4873 is not currently correct.  Change code or doc?

In Python/initconfig.c, the -R option sets config->use_hash_seed to 0. It overrides PYTHONHASHSEED env var, as documented at:
https://docs.python.org/3.10/using/cmdline.html#cmdoption-R

IMO it's the expected behavior. Cmd line must have the priority over env vars.

Which doc is wrong?
