Re: A new feature request - parser add_mutually_exclusive_group - add 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.

  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!
