You'll have to get freaky with python internals.

>>> class A:
...    def dowork(self):
...        name='Lucas'
...        work=['aaa','bbb']
...        work1=[]
...        work2=[]
...
>>> A.dowork.im_func.func_code.co_names
('name', 'work', 'work1', 'work2')
>>>

the builtin module inspect [1] wraps up some of these things but I
don't see a method to get local var names, like above.
