+1.

Any reason not to do something like:

from argparse import actions ... parser.addargument('--plot', actions.storetrue) Basically a small namespace for the constants.

-1.

That ignores the value to the programmer in specifying keyword arguments (there are a lot of arguments to the function, making keyword arguments a better mean-what-you-say choice). To be equivalent, it would have to be:

from argparse import actions
# ...

parser.add_argument('--plot', action=actions.store_true)

I prefer the string values.
