Are you sure that you really need that single-element list?
>>> def getvinfo2(vars, v):
... for n in vars.keys():
... if vars[n] is v:
... return n, v, type(v)
...
>>> getvinfo2(locals(), a)
('a', 1, <type 'int'>)
>>> getvinfo2(locals(), b)
('b', 2.2999999999999998, <type 'float'>)
>>>Now, making that second parameter a list would enable you to do this for multiple local names with a single call, but getvinfo() doesn't try to do that...
Don't forget, in Python, all names are references. You only have to be careful when you start re-binding names...
