Yeah, copied.  Just as in:

>>> a = 3
>>> b = a
>>> a = 5
>>> b
3
>>>



given b.py:

##########################
thing = 0
##########################

and a.py:

##########################
from b import *
import b

print thing
print b.thing

b.thing = 1
print b.thing
print thing
###########################
