an ugly file-reading pattern

I have been working with perl and java for quite a
few years now and I am currently actively looking
to replace perl wit something better, a language that
promotes software engineering principles. I was
directed toward python and ruby, I have been
working with both of them for a couple of weeks now.
And now for the python question:
Suppose that I'm looking for a way to
read lines from a text file:
now there is the readlines() method
that slurps everything up (no good for me
since I don't like to build into my systems
implicit assumptions about filesizes)
if I choose to process the file line by line
the "Learning Python" book advises me to use the
following atrocity:
while 1:
line = file.readline()
if not line: break
Maybe I'm picky here but having to start an infinite loop
then needing a conditional to break out of it is
anything but an elegant pattern.
This has left me wondering about python,
cheers,
Istvan.
