If the original poster is already running a UNIX-like system, then
there's already an easier way to do this; redirect stdout to /dev/null
from the shell:

	./myScript.py > /dev/null

As for non-UNIX systems which wouldn't have a /dev/null to open anyway,
there's an easier work around; just create a file-like object that does
nothing:

	class NullFile:
	    def write(self, data): pass
	    def writelines(self, lines): pass
	    def flush(self): pass
	    def close(self): pass

and then

	sys.stdout = NullFile()
