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:
