Use the locals() function instead of globals().

Thanks by the way, I was wondering how to do this also, your post, and 
Daniel pointing out 'is', helped me work this out.  There should be an 
easier way that doesn't require stepping though the name list.

This doesn't use lists in the same way, but I think it answers your 
question.

def getvinfo(vars, v):
     """
     vars is locals()
     v is [varable]
     Use an one item list to pass single varables by reference.
     """
     for n in vars.keys():
         if vars[n] is v[0]:
             return n, v[0], type(v[0])

a = 101
b = 2.3
c = True

print getvinfo(locals(), [a])
print getvinfo(locals(), [b])
print getvinfo(locals(), [c])

 >>>
('a', 101, <type 'int'>)
('b', 2.2999999999999998, <type 'float'>)
('c', True, <type 'bool'>)


This could be useful for printing error messages and debugging info.
