I recall having some issues with local variables sometimes, but actually
your example works fine for me:



def test():
    foo = "foo"


    import pdb; pdb.set_trace()

    print foo

test()


And the session:

$ python /tmp/test.py
> /tmp/test.py(9)test()
-> print foo
(Pdb) pp foo
'foo'
(Pdb) foo = "bar"
(Pdb) n
bar
--Return--
> /tmp/test.py(9)test()->None
-> print foo
(Pdb) c
