New submission from Tristan Fisher:
It's my understanding that giving the action="store_true" to an argument in
argparse defaults to False. When using non-double-dashed/positional arguments,
the argument resorts to True (even if explicitly marked default=False).
I've attached a minimal example, but, for clarity, the relevant line is as such:
parser.add_argument("meow", action="store_true", default=False)
I realize that this might strike some as an odd usage, and I always have the
option of using "--meow," but I found it odd that a positional argument is
always True, even if not specified in sys.argv.
