I'm sorry, but that makes no sense to me at all. I don't understand what
you are trying to say.
You do understand that exceptions aren't just for errors? They are raised
under specific circumstances. Whether that circumstance is an error or
not is entirely up to the caller.
try:
n = mylist.index('fault')
except ValueError:
print "All is good, no fault detected"
else:
print "Your data contains a fault in position", n
People get hung up on the idea that exceptions == errors, but they
aren't. They *may* be errors, and that is one common use, but that
depends entirely on the caller.
