Yes I think you may have misunderstood my orginal post Luke. The portion of code I gave will ensure each time this line is written it just writes over the previous line ( when printed to the console and \r is not windows specific). As I said, I have tried numerous ways to write these commands to a logfile so the line will just be written over ( the method you gave will just create a newline per iteration of the loop), as it is if I direct the output to the console.
The section of code I gave is contained within a while loop, which is constantly checking for something to appear on a website. It simple prints out a line, letting the user know how long it has been waiting for. On the console this will just appear as one line ( each iteration writing the line over the previous one). In the logfile, this wil be a new line for each iteration of the while loop.
To answer Kents questions, I previously had these outputs going to a logfile which could just be tailed. I now want to change the way I display the logs created. I firstly create a logfile within an apache server, this logfile appears as a link on a frontend website beside a corresponding test name. I then want to output all log messages to this one file. For what I am doing, it would be extremely useful for any number of users to just click on a link and have access to what is currently being run on the backend, in realtime. Using both logging and plain write messages, the output provides information on what function, script etc is running. There is one very large script, that runs a large number of other scripts to test and change data on a website.
So my problem is I want to be able to have this one logfile accessible from the web and not have a huge amount of one line messages appearing ( within the various while loops), which just let the user know how long the script has been waiting.
Kent, I will try your method and I hope this explains my objective a little better.
Thanks
Kieran

I don't understand what the commas atthe end of your print commands are for.
Nor do I understand what you're trying to do.
Are you trying to redirect stdout to a file?
why bother doing this?
why not just do
from time import sleep
from random import randint
f = file(" log.txt","a")
while x < y:
f.write("\nNow waiting %s seconds\n" % randint(0,4))
f.close()
Or do I misunderstand what your objective is?
Also, I believe \r is windows-only, and you should use \n all the time,
or \r\n.
