Allow the Users to select their preferred way to provide commands arguments
For example, the user should be able to provide -p or --pad

Solution
Make all ArgumentParser's arguments support full and short versions (wherever possible):
Example:

parser = argparse.ArgumentParser()
parser.add_argument('-n', '--name', help="help msg")
