To realize what you want to do, you can add the elements to be removed to
another set.
On each iteration, verify that the current element isn't already in the set
of elements to be removed, and after the loop, clean the first set using
the elements of the second one.

I need to iterate over a Set whose elements will be deleted in the process.
However, some deleted elements are included in the iteration, e.g. the
element 4 in the code below.
According to the following, it is
Modifying a collection while iterating over it is likely to cause strange
things to happen. I have worried about this from time to time but I'm not
sure how to fix it. One approach is to advance the state in next before
returning the element, then always return an element that you know must be

In Python it's bad to insert/delete items as well. And people do get
bitten. That doesn't mean it shouldn't be fixed though.

eh? the code tries to delete all entries and, instead of an exception,
data remains.
are you saying that's not trashing because the remaining value was there
initially?

i guess what i meant was something more along the lines of - the output
