Always report the specific problem. Saying "why this not work?" does not 
help.

What happens when you run this program?

When I do I get:
  File "J:\pipelines\cubed.py", line 11, in <module>
    if isCube(soma):
NameError: name 'isCube' is not defined

When I examine the program I'm not surprised to get that exception.
