[issue16970] argparse: bad nargs value raises misleading message

[Guido van Rossum]

Guido van Rossum <guido at python.org> added the comment:

The 3.8 backport will land automatically once the tests pass.

The 3.7 backport ran into some trouble, probably a simple merge conflict.

Sushma do you want to try your hands at this?  It probably requires some learning about Git branches.  We can also skip this, it's only an improved error message after all, and you can try something more fun instead.

The 3.6 branch is closed except for security fixes, which this isn't.
