Using the add() Method: Adding Single Elements to a Set

You can also add elements to a set. To do this, there's a specific add() method. It's important to note that with this method, you can add only one element at a time. So, if you want to add 4 elements, for example, you'll need to use this method 4 times. Let's check out an example.


              
1234567891011

            
# Creating an empty set
favorite_movies = set()
print("Initial set:", favorite_movies)  # Output - Initial set: set()

# Adding movies to the set
favorite_movies.add("Inception")
favorite_movies.add("Interstellar")
favorite_movies.add("Tenet")
favorite_movies.add("Dunkirk")

print("Updated set:", favorite_movies)  # Output - Updated set: {'Interstellar', 'Dunkirk', 'Inception', 'Tenet'}

The add() method is best used for adding single elements.
