Newbie question about file input

Not necessarily.  The use of "while True" at least signals that the loop
exit condition isn't at the top.  I suspect, though, that this is a "style"
question, and as such there will be a Mighty Discussion about it...

Arguably so, but you do the "next loop statement" (in this case,
"line=zf.readline()") in two places.  Redundancy.  Chance of changing one
and forgetting to change the other.  Eww.

But:
for line in zf.readlines():

is even neater
