I found a corner case on the find sum in list that I overlooked. If the list is [1,2,5] and the number is 4 I will return true because I am looking through the whole list for K-element and will of course find element. I was so happy to get a single line that worked, I am wondering if I can fix it and still keep it one line?

I know count may work better than any, or some other logic to handle the special case of K-element == element
