global name space and importing

[Curtis Jensen]

How come the global declaration works when I define it from withing the
interpreter, but not from within a file that I import?  See following
example.

file: foo_bar.py:
def foo(i):
  x = i

def bar(i):
  global y
  y = i

Python interpreter:
>>> from foo_bar import *
>>> bar(0)
>>> print y
Traceback (innermost last):
  File "<stdin>", line 1, in ?
NameError: y
>>> def other(i):
...   global z
...   z = i
...
>>> other(5)
>>> print z
5
>>> ^D
