Hi, Thanks for the incredibly quick responses! The os.isatty() call (and sys.std*.isatty() calls as suggested by Chris Angelico at http://mail.python.org/pipermail/python-list/2012-April/1291048.html) work perfectly for this job! I might have to do some testing later on Windows though to see what happens when the ansi escape characters are not supported.
