That's a Windows problem. When you execute the script as itself
(either as you do in the command line, or by double-clicking on it),
it doesn't have valid standard handles.
You have to invoke Python explicitely:
python simple_markup2.py < test_input.txt > test_output.html
(you may need to specify the full path to python.exe, or add the
directory where Python is installed to your system PATH).
I use stdout this way all the time, with no problem (python 2.6,
Windows XP). But as you point out, stdin redirection doesn't seem to
work using the file associations. I do get a different error though.
When I look at sys.stdin, it shows an open file, with handle of zero,
as expected. But when I do a raw_input(), it gets:
EOFError: EOF when reading a line
I think the error depends on the specific OS version/service pack. But
at least on XP this appears to fix it:

Thanks for the link. Looking at that one, it indicates that Windows
2000 fixed it in SP4, and XP fixed it in Sp1. But I'm already running
XP SP3, so I wonder if it's something new.
Matt, what OS version are you running, and exactly what is happening
when the error occurs? (you should be able to figure that out from the
stack trace)
