and I have the following Test.py:

test_var = 5
from Test import a,b,c
is equivalent to:
import Test
a = Test.a
b = Test.b
c = Test.c
which I hadn't been aware of. Then the link between a and Test.a (eg.
Test.test_var) is broken (unless Test.a is something like a list so both
still refer to the same data. But assignment to either - not an in-place
mod - will break the connection).
Just to clarify: there is no link directly between a and Test.a, except that
both refer to the same object.
OK, but I meant the link there have been if 'a' was in fact a synonym
for Test.a.
Just as here there is no link between x
and y:
x = 12
y = x
(And that's a good illustration of why 'y' isn't a name reference to
'x', referring to the "...ducks limp" thread. But best not to rake it up
again...)
