Python 2.2.1 (#34, Jul 16 2002, 16:25:42) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.stdout.isatty()

Have we discovered the mystery of life at last? "True" is 64? :)
NOTE: PythonDoc says "isatty" is Unix only.

PDCurses binding for Python.

Thanks to everyone for their answers! I'd like to thank the Academy, the
Screen Actor's Guild and especially, Timbot, who helped make it all possible
