Hello. Indeed the doStuff function in the doStuff module can't do 'a.b
= 0' (the double dot was just a typo, right?) because it doesn't know
anything about an object named a.
I think the right solution would be not to use 'a' as a global
variable, but rather to pass it as an explicit parameter to the
function.
In module doStuff:
def doStuff(a):
# some calcs
a.b = 0
In the main module:
import doStuff
# ...
doStuff.doStuff(a)
