Another benefit of strings is that data-driven argparse configuration
will usually be slightly simpler.

This could easily be fixed with
from argparse.actions import store_true
An option would be
parser.add(actions.StoreTrue('--plot'

I've added it to the argparse bugtracker, along with my suggested spelling
add_flag():

I like them too. I don't see anything unpythonic about them.

Boolean flags are a common enough case that I'd be inclined to add a wrapper
method, so you could just say:
parser.add_bool_argument('--plot')
As you can always fall back to the more general

(I'm looking at things such as SEEK_SET and friends)
Strings are certainly preferable to ints, one reason being that
they display as something meaningfu
I don't believe argparse's action specification scheme is bad either, but

It isn't ideal, but having to grab constants from the module isn't ideal

What else would you propose?
FWIW, this is
I generally enjoy argparse, but one thing I find rather
ugly and unpythonic.
parser.add_argument ('--plot', action='store_true')
Specifying the argument 'action' as a string is IMO ugly.
