Usage of argparse with a single option

[Otbredbaron]

Hi, I'm trying to use argparse to handle a single command line option, this is the code that I wrote:

#!/usr/bin/env python3
import argparse

parser = argparse.ArgumentParser(description='foo')
parser.add_argument("Option", choices=['true','false'] )
args = parser.parse_args()
if (args.Option == 'true'):
    print('something')
else: #then it's false
    print('something else')

I'd like to know if it's correct or there's a better way to do this
