My clunky solution to this problem in general is by defining a class:

class StandardOutputEater:
     def write(self, string):
         pass

Then when I need to disable standard output:

#turn off standard output
saveout = sys.stdout
sys.stdout = StandardOutputEater()

When you want standard output again, call:

sys.stdout = saveout

This gets the job done in all such cases.

This is also useful to quickly turn off some self-reporting messages every 
once and a while.  (Such as when you demo some code still under 
development to an interested party.)
