Hmm...  I was just talking about using iter(f.readline, ''), but it does 
appear that isatty returns True for sys.stdin in the interactive prompt:

ActivePython 2.4.1 Build 245 (ActiveState Corp.) based on
Python 2.4.1 (#65, Mar 30 2005, 09:33:37) [MSC v.1310 32 bit (Intel)] on

Type "help", "copyright", "credits" or "license" for more information.
py> os.isatty(sys.stdin.fileno())
True

and at least some other things return False:

py> os.isatty(file('temp.txt').fileno())
False
