That's because you ask the wrong question.
[1,2] in xdic[item] doesn't check to see if 1 is in the list, then if 2
is in the list. It looks to see if one of the items is *exactly* [1,2].
>>> [1,2] in [1,2,3,4]
False
>>> [1,2] in [1,2,3,4, [1,2]]
True

for key, value in xdic.items():
if 1 in value and 2 in value or 3 in value:
print key
