The exception gets caught and ignored, so I would rather say
it is "thrown away" than that the "error is cleared".

The point is that the standard for-loop actually used by
the original poster is implemented in C (not in Python). So
to understand why this implementation of the for-loop does
what it does I have to look at the C level. Of course giving
an explanation as an equivalent Python code snippet (like the
one above) is a nice way to put it. But I still don't see
where you object to the term "error is cleared" when that is
what actually happens in the Python interpreter.
