New submission from Serhiy Ivanov:
have 1.py as:
import argparse
import sys
print (sys.argv)
parser = argparse.ArgumentParser(prog='demo')
parser.add_argument('--host -h', help='host for the server of %(prog)',
nargs=1, required=True, metavar='<host>')
parser.add_argument('--port -p', help='port for the server of %(prog)',
nargs=1, required=True, metavar='<port>')
parser.parse_args(sys.argv)
and run C:\Python34\python.exe 1.py -h 1.
Will obtain:
