Hi,
I created a class and placed it into another file
then imported that file into my main script but it comes up saying that the
variable 'myclassname' doesn't exist.
Both files are in the same directory and the class works fine when used in
the same script.
Here is what I have. Can anyone look over them and see what im doing wrong?
Im still new to classes/python
1- the stand alone file
2- module w/ class definition
3- main script that imports module and calls on class 'Cloud'
thanx,
##############ERROR- when trying to use imported module

NOW THIS IS WHERE I IMPORT AND CALL THE CLASS FROM THE MAIN SCRIPT

#Import any needed modules

import time
import string
import SDsimLib #name of the file w/ class is defined
##lots of code here
#import cloud w/ the new Cloud class
cloud = Cloud('cloud',[1,2,10])
