python2.4 generator expression > python2.3 list expression

[snacktime]

I need to convert a generator expression to a list expression so it
will work under python 2.3.

I rewrote this:

for c in range(128):
  even_odd = (sum(bool(c & 1<<b) for b in range(8))) & 1

As this:

for c in range(128):
  bo = [bool(c & 1<<b) for b in range(8)]
  even_odd = sum(bo) & 1


Seems to work, is there a better way to do this?
