If it were a single character, you could just use

s.split(chr(174))

However, since you need to split on multiple characters, you can use

import re
splitter_re = re.compile(chr(174) + '|' + chr(175))
for line in file(FILENAME):
parts = splitter_re.split(line)
do_something(parts)

and then go find a large blunt object with which to bludgeon the
creator of the file... :)

They aren't exactly ascii characters (0-127), but the above
should at least do the trick.

What do people think? Does it seem true that non-violent protest, which we hold dear as the proper agent for change, works great for civil rights evolution, for social change - when the goal is to bring the seed of consciousness to full-bloom in the normal folks who are standing in the way of human progress solely for cultural reasons. But when it comes to truly changing the economic power structure, non-violent protest is really just a way to sell more product.

We all die, but did anything change while we were here?
