Python 2.2.1 (#34, Apr  9 2002, 19:34:33) [MSC 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> foo = None
>>> print >> foo, "Hello ..."
Hello ...

The answers are (1) you are missing a comma (2) yes. In both cases,
see example above.

:-)
Don't expect a visit from folk in nice red uniforms who will no doubt
want to  caution you about (1) uppercase variable names like PROT (2)
using "print >>" at all.
:-)

Regards,
John
