When I do that assignment there seem to be 5 references to that object, two
of them are dictionary keys (what's the name of a dictionary key?), and two
are dictionary values. the last one is of course x. Any of these seem a
reasonable answer to the question, but how the code is supposed to tell
which name is the one the user wanted is another matter.
>>> import varname
>>> x = 57
>>> for s in varname.object_info(x):
... print s

opcode.opmap['INPLACE_MULTIPLY']
encodings.cp850.encoding_map[57]
encodings.cp850.decoding_map[57]
dis.opmap['INPLACE_MULTIPLY']
__main__.x

When I repeat the experiment in Idle the cp850 encoding entries disappear so
I only get a choice of 3 'names'.

My code thinks its name is <...>, but then that's just my code:
>>> l = []
>>> l.append(l)
>>> for s in varname.object_info(l):
print s
__main__.l
<...>
>>>
