[Tutor] Re: for/else question

        for pattern in patternl:
            if elem.find(pattern) >-1:
                break
        else:
            backl.append(elem)


To me, this says exactly the opposite of what it does... I read it as:
"do something for every element in the list,
otherwise, if I can't go through the entire list,
do that."

I suppose there may be times when this is the most concise
way to write it, but I would never write it like this.
