Listing variables

[vsoler]

Say that a have:

# file test.py
a=7


At the prompt:
import test
dir()

I would like to see the variables created in the test namespace.
However, variable "a" does not appear in the list, only "test". Since
I know that var "a" is reachable from the prompt by means of test.a,
how can I list this sort of variables?
