Set add() in Python

# Introduction to Sets in Python Python's built-in set type implements the mathematical set abstraction. A set is an unordered collection of unique elements. It is mutable and can be modified after creation. It is often used to store data in a more efficient way than a list or a dictionary, since it is not necessary to look through all the elements to check for duplicates. Sets provide a number of important operations, including membership testing, union, intersection, and set difference. Sets also have the ability to add and remove elements, as well as iterate over their elements. This article will cover the `add()` method, which is used to add an element to a set. It will also explore some of the other operations that can be performed on sets.

The **add()** method in Python is used to add two or more elements to a set. It takes two or more elements as arguments and adds them to the set. **Syntax** ``` set.add(element1, element2, ...) ``` **Example** ``` # Declare a set colors = {'Red', 'Green', 'Blue'} # Adding an element to the set colors.add('White') # Printing the updated set print(colors) # Output {'Red', 'Green', 'Blue', 'White'} ```
