[Python-ideas] argparse: mutually inclusive arguments

Hi All, I've been using the argparse library for a long time and one use case that repeatedly shows us is the need to have two arguments appear together i.e either both appear or none of them appear. I'll refer to these as *mutually inclusive* in contrast to the existing *mutual exclusive* feature

I don't think we want to add a new dunder just to make it easier for people to abuse bitwise operators instead of using the `!=` operator. -- Steve ___ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le
