 Hi again in this lesson. We're going to talk about that how to add an element to a set in Python programming language First, let's make some set let's call it my set and Let's populate it with few numbers one two three four and five so our set He has five Elements one two three four and five if we want to add to our set some new element We'll use method add With that method we can add an element to a set so we want to add to this set some new element, but What will happen if we try to add an existing element if we in this example want to try to add number two which is Already inside our set. What will happen? If we try to see our Set after calling this method We will see that our set Has just one Number two so if you try to add number that already exists in That set nothing will happen. You will not have situation like that to have Two times number two because you added again because if You try to think a little bit about it set is an unordered collection of unique elements So elements inside our sets needs to be unique so we can add some new element by again using method add but We want to provide as an argument element that is not yet Inside our set and if we try to add element seven which isn't in this set and If we try to see our new resulting set We will see that our Number seven is was added to our set So if you want to add new item To the set you can use method add to add This element that's all in this video See you in next next lesson
