AFAIK, no. Nor am I sure why you would want to - None is a singleton so
there can only be once instance of it at a time. None is only printed when
you're working in the interactive interpreter - if you write the program in
a .py file and execute it you won't see the 'None' unless you print the
result (which would indeed be None!)
