Adding Items to a Set

You can add items to a set using the add() method for single items or the update() method for multiple items.

Using add()

Example: Adding a Single Item

# Adding a single item to a set
numbers = {1, 2, 3}
numbers.add(4)
print("Set after add:", numbers)

Output (Order may vary)

Set after add: {1, 2, 3, 4}

Using update()

Example: Adding Multiple Items

# Adding multiple items to a set
names = {"Karthick AG", "Durai"}
names.update(["Vijay", "John"])
print("Set after update:", names)

Output (Order may vary)

Set after update: {'Vijay', 'John', 'Karthick AG', 'Durai'}

Explanation: The add() method adds a single item to the set. The update() method can add multiple items, which can be from lists, tuples, or other sets.
