Arrays, Got Me Confused

[rishi pathak]

HI,
 You will have to import Numeric module
Add
from Numeric import *
to the script
 For the second question:
Suppose you wrote the code for your class in firewall.py
and your main script is main.py
Put the file firewall.py in the directory where you have main.py
Then in main.py do :
import firewall.py

To create an object of class Firewall
firewallDemo=firewall.Firewall()
May be this will help
