Okay, when I run a test program:
import Graph
graph = Graph("1")
I got:
Traceback (most recent call last):
File "E:\test\Graph\test_graph.py", line 3, in ?
graph = Graph("1")
TypeError: 'module' object is not callable
Oh, wait....silly me. Should have been:
from Graph import Graph
<bonk, bonk, bonk>
Must be a Sunday.
Thanks,
