Hi,

Please look at this Stack Overflow post: https://stackoverflow.com/questions/78722378/parser-add-mutually-exclusive-group-how-can-i-set-a-default-value

1. Is there a way to add a default to parser add_mutually_exclusive_group groups - a value that will be set by default? In this case I
want test-default-languages=True to be set as a default.

2. I tried to subscribe to Python-ideas [email protected], but I
can't login to
https://mail.python.org/mailman3/lists/python-ideas.python.org/. Although I
did login to https://mail.python.org/mailman/options/python-list . Do I
have to create a new account?

Thanks,
Uri.

I am not aware of such a possibility. But you could write a function
to parse the arguments using argparse, then inspect the parsed_args,
and modify them to reflect your default if no other argument was
detected. However, I have no experience with using argparse at all,
so it is well possible that someone who is proficient in argparse
might actually know how to set a default value there!

It might be necessary to once create an account for the new
Mailman3 system. As I have no experience with mailing lists
whatsoever, this is just a wild guess!

I looked at the linked SO post and it seems to be a feature suggestion
for the argparse library. Python's bug tracker is currently at:

https://github.com/python/cpython/issues

You might want to open an issue there with a concrete proposal.
