Hi Karen,
if I have a file called foo.py =
def la()
return "la"
x = 15
I can do the following in bar.py =
import foo #Notice there's no .py extension!
j = foo.la()
print j
print foo.x
> la
> 15
Hope that helps
Liam Clarke

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
