unable to create "subgroups" under mutually exclusive group

[Liang Wang]

Dear developer,

I am new to Python and have a question: is there any way in argparse
to create "subgroups" under mutually exclusive group? For example, I
would like to group four options a, b, c, and d into two mutually
exclusive subgroups ("a","b") and ("c","d"). And within each group, I
hope both of the arguments are "required", for example, if "--b"
presents, then "--a" should presents.

Seems to be the issue raise here:

There is now a feature request for something like this:

http://bugs.python.org/issue11588

But it probably won't make much progress until someone writes a patch. ;-)
