for method_name in ['read1', 'read2', 'read3']:
   for dev in devs:
     try:
       meth = getattr(dev, method_name)
     except AttributeError, e:
       # should not happen, but we want to handle it anyway
       your_code_here()
     else:
       try:
         meth()
       except (SomePossibleException, SomeOtherPossibleException), e:
         print e
         # do what's needed to remove dev from devs
         # paying attention not to screw the looping machinery...
