 Hi again, in this lesson we're going to talk about that how to remove an arbitrary item from the set in Python programming language. First let's make some set, let's make set with few values with elements 1, 2 and 3. If we want to remove an arbitrary item from the set, we will call method pop. That method removes and returns an arbitrary set element. And if our set is empty, we will get key error error. So let's pop our element and now we don't have any more number 1 in our set, let's check it. So now we have just elements 2 and 3. Let's now try to call this function again and now we removed element 2. Now our set has just number 3. Let's remove and that element by calling pop function and now our set is empty. Now let's try to remove an arbitrary element from our set when our set is an empty set. And of course we will get an error. We will get key error pop from an empty set. So in this lesson we talked about pop method which removes an arbitrary element from a set in Python programming language. That's all in this lesson. See you in some other lesson. Bye-bye.
