The above would be a generator expression, and requires
Python 2.4. It shouldn't cause a SyntaxError unless there is
some mistake I'm not seeing (or you missed something in
the copy & paste).

You need to create a list (e.g using a list comprehension)
rather than a generator, probably:

c = [i.id for i in b]
c[0] = "Fred"
