RTFM. There are API functions to create an empty list [] and to append
objects to a list. PyList_something(), I think.

You might want to return this as a Python string, even if it's just random
octet data garbage. Depends on what that data really represents, but it's a
common idiom, and modules like struct and array expect their data to be
strings. Note that Python strings may contain NUL bytes.
