Thank you, everyone. Defining a new type for this is just what I needed. No
additional modifications are necessary on top of this new type.

You could try declaring a type converter and using the type= parameter of
add_argument. Your type converter could look something like:
def expanded_path(arg):
return os.path.expandvars(arg)
Would that work?

I had forgotten all about os.path.expandvars. Note, however, that that
function is very naive:
os.path.expandvars('$HOME')
'/home/rdmurray'
That is, it is doing unconditional substitution, not parsing shell syntax. It
should work well for simple
Nat Hillard added the comment:
Indeed these are all valid points, and as a zsh user myself I certainly
considered the alternative shell issue. That said, if it were at all possible,
through a combination of os.environ / shlex, subprocess, and even `source` if
necessary, to offload this
