# importing required modules
import argparse
 
# create a parser object
parser = argparse.ArgumentParser(description = "An addition program")
 
# add argument
parser.add_argument("add", nargs = '*', metavar = "num", type = int,
                     help = "All the numbers separated by spaces will be added.")
 
# parse the arguments from standard input
args = parser.parse_args()
 
# check if add argument has any input data.
# If it has, then print sum of the given numbers
if len(args.add) != 0:
    print(sum(args.add))
