Hello list,
Recently someone asked me this question, to which I could not give an
answer. I'm hoping for some insight, or a manual page. What follows is
python 2.6.
The problem is with the difference between
from test import *
and
import test
First things first. Here's the code to test.py:
a = 3
def f():
global a
return a
Now, in the interactive interpreter:
>>> from test import *
>>> a
3
>>> f()
3
>>> a = 4
>>> f()
3
in a second session:
>>> import test
>>> test.a
3
>>> test.f()
3
>>> test.a = 4
>>> test.f()
4
Somehow, in the first session I cannot modify the global variable a
returned from f, but in the second session I can. To my eye, the only
difference seems to be a namespace. Can anyone shine some light on this
matter?
Thanks,
Stefaan.
