well, a bit more canonical would be:
...
while buf:
# do something
...
instead of comparing len(buf) with 0. But that's a minor detail.
One could use this:
with open(filename, "rb") as f:
for buf in iter(lambda: f.read(1000),''):
do_something(buff)
but I don't really like a lambda in there. I guess one could use
functools.partial instead, but it still looks ugly to me. Oh, well, I guess I
also want to see the canonical way of doing it.
