Look at the 'new' module. It's in the Library Reference under
Python Runtime Services. You'll need to wrap the byte string
with 'code', and then wrap that with 'function'.

As someone else pointed out, there are a number of other
parameters you'll need to supply, and some of them aren't
at all obvious. You may find the disassembler (documented
under Python language services) to be helpful in figuring
some of them out.
