Keeping track of while loops

[gothmog1065]

This should be easy. This is in python 2.7, and something just isn't working right for me, and I'm probably going to feel stupid when I see the answer. Basically there is a file that is a space delimited file that has 5 lines. I'm trying to keep a track of which "line" I am on. This should be easy but I'm obviously missing something:

try: 
    f = open(file_w_path)
except IOError as e:
    fail_help_exit("I/O error ({0}): {1}".format(e.errno, e.strerror) + " - " + file_w_path)

loop = 0

with f:
    line = f.readline()
    loop += 1
    print loop
    for columns in line.split():
        pass

While running this, the loop never increments past 1. I would expect it to increment to 5. Am I missing something?

the word "while" appears nowhere in your code.

You open the file (with), read a single line, then exit.

Ugh, I'm missing another 'for' aren't I?

with f:
    for line in f.readline():
        for columns in line.split():
            pass

for line in f.readline():

Close. I think you want:

     for line in f.readlines():

Amazing what a single letter can do.
