Re: How to do this in Python?

One could use this:
with open(filename, "rb") as f:

This is by far the most pythonic solution, it uses the standard 'for'
loop, and clearly marks the sentinel value. lambda may look strange
at first, but this kind of thing is exactly what lambdas are for.
Judging by the other responses, it would seem that few people are
aware of the two-argument 'iter'.
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.
I believe you've just written it.
