A true hackerish version perhaps:

    bc = [124, 0, 0, 114, 37, 0, 116, 0, 0, 124, 0, 0, 106, 2, 0, 100, 1, 0, 131, 1,
          0, 124, 1, 0, 106, 1, 0, 124, 0, 0, 131, 1, 0, 131, 2, 0, 83, 124, 1, 0,
          83]
    fact = type(lambda:0)(type((lambda:0).func_code)(2, 2, 7, 0,
                   ''.join(map(chr, bc)), (None, 1), ('fact', '__mul__', '__sub__'),
                   ('x', 'acc'), "n/a", "fact", 0, ""),
              globals(), "fact", (1,))

while I know this is a joke I would argue that this is in no way hackerish, this is an asshole version. Basically a middle finger to anyone who wants to work with your code. Also anything but pythonic. (please note this not meant to be an insult to the parent commenter)

It is hackerish to the extent it demonstrates a knowledge of python's internals, however maybe it would better be described as being written by a former assembly programmer. Also, you might be interested in the fact that Paul Graham argues that his dream language would have inline bytecode. It probably wouldn't be written as a list of integers though.

As for this not being pythonic, at least its not self modifying or anything fun. I did once see a talk on obsfucated python that used decorators to implement a Turing complete language, so this is hardly the worst abuse of python ever.
