I wouldn't have a problem with
if not i: break
in Python, as long as the condition is short. In something that reads
from a socket until the other end closes, for instance, I'm fine with
this:
while True:
data = sock.read(1024)
if not data: break
do_stuff_with(data)
which will stop as soon as sock.read() returns "", which it does when
the other end is gone. (I wrote something doing exactly this today,
and did exactly this. Probably could have made the code a bit simpler
if I could depend on Python 3.3, but it has to run on 2.7 and maybe
2.6 so I had to stick with their facilities.)
Yes, it's two statements, but a list comprehension is a whole pile of
statement-y things, and that's usually a single line. If it's doing
one conceptual action, it's okay to not split it.
