or, if processing the file as a list of lines doesn't work, the standard
idiom is:

fh = open("file", "r")
while 1:
    line = fh.readline()
    if not line: break
    # do stuff with line


I'm not really very fond of "while 1" constructs, but since the break is
right there next to it, it's not too bad, and I think a little better
than what I used to do:

fh = open("file", "r")
line = fh.readline()
while 1:
    # do stuff with line
    # there could be a LOT of code here

    line = fh.readline()
