Just try/except:

try:
   #put your code here
except IOError:
   #don't save, print a message, whatever you want to do
   #if you want to propagate the error, uncomment next line
   #raise

To be considered stupid and to be told so is more painful than being called
gluttonous, mendacious, violent, lascivious, lazy, cowardly: every weakness,
every vice, has found its defenders, its rhetoric, its ennoblement and
exaltation, but stupidity hasn’t. - Primo Levi
