Feature or enhancement

Proposal:

Most of the-X options (https://docs.python.org/3/using/cmdline.html#cmdoption-X) can be configured via an environment variable, but not-X frozen_modules.

This makes it harder for environments that you don't have the control over the flags passed to the Python interpreter.

#98697 also includes a use case forcrossenv, but the issue was closed because it was not in time for Python 3.11.

I'm proposing aPYTHONFROZENMODULESPYTHON_FROZEN_MODULES environment variable to be added for Python 3.13, which has the equivalent meaning of using-X frozen_modules.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

#98697 is the same request, but closed due to not in time for Python 3.11.
