If, however, you are on Windows NT, you will find that a bug in the command
processor (NT's, that is) stops redirection from working on commands where
the executable is deduced from a file extension. Therefore in this
environment you need:

python myprogram.py < my_input > my_output

This is also required on Win95/98 (except cygwin/bash, which is pretty
Unix-like on all Windows flavors).
