command line parser can not handle blank space when call python in sh

a.py:
for arg in sys.argv:
    print arg

b.sh:
python a.py $*

situation 1:

python a.py "123 456"

get:

123 456

situation 2:

/bin/sh b.sh "123 456"

get:

123

456

It seems "123 456" will pares in two args,how can i modify b.sh, make a.py can treat "123 456" as one arg.

Argparse sample related to my comment. Greatly simplifies legwork required 

import argparse

parser = argparse.ArgumentParser(description='Test ')
parser.add_argument('first',help="The First argument", type=str)
parser.add_argument('second',help="the second argument",type=str)

args = parser.parse_args()

You need quotes:

python a.py "$*"

Also, if you use "$@" instead of "$*" it will expand to a multiple arguments.
