Is the output you are talking about from print commands and/or 
sys.stdout.write(...) calls, or is it error messages?  Unix and Windows 
processes have two standard channels for writing messages, stdout and
stderr, which Python maps to sys.stdout and sys.stderr.  The redirection
you show only redirects stdout/sys.stdout.

On Unix (and reportedly Windows NT) you can write:

    python hello.py >out.txt 2>errors.txt

which separates the output channels, or

    python hello.py >out.txt 2>&1

to combine them in the file.  Unfortunately this does not work on Win9X,
but there is a program available called stderr which combines the two 
channels.  Get it from:

IF NONE OF THIS HELPS YOU... please post your hello.py so we can
inspect it.

I'll have to look at the FAQ, I'm not sure why Linux would have a problem 
with it.
