Shell Programming and Scripting

Hi, I had to create a new thread as the old thread had to much of confusion

I have two files shashi.sh and py.py
I want to pass a variable from shashi.sh to py.py. How do i achieve that ?.

shashi.sh

export X=12
echo "$("pwd")"
echo "$X"
exec python py.py "$(X)"

py.py

#!/usr/local/bin/python
import os
print "Now, we're going to add up some numbers."

if X < 100:
    print input("Total is not yet over 100, enter another number: ")
else:
    print ("That's it, you're done!")
