The "right" way to do this is:
for line in file ("filename"):
whatever
The file object returned by file() acts as an iterator. Each time through
the loop, another line is read and returned (I'm sure there is some
block-level buffering going on at a low level).

You probably want something like:
for line in file ("filename"):
if skipThisLine:
continue
