How to Detect Use of Unassigned(Undefined) Variable(Function)

Is there a script/module to detect the use of unassigned
(undefined) variables(functions) in python. e.g. can I detect the
problem on line 3 automatically :-

i = 1
if i == 3:
print o
print i

Thank You,
++imanshu

pychecker returns "test.py:3: No global (o) found" for the above, and
can be found at http://pychecker.sourceforge.net/

There's also pylint and another one whose name I can't remember...
