Use the following line to instantiate a instance of Cloud in your stand alone program...

#import cloud w/ the new Cloud class
cloud = SDsimLib.Cloud('cloud',[1,2,10])
        ~~~~~~~~~

If you wanted to access Cloud directly in your namespace, without having to use the ModuleName-Dot-Class format, change your import as follows...

from SDsimLib import Cloud

Keep it up!
David.

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,
