Python Coding Challenge - Question with Answer (ID 061126)

 

Explanation:

1. Creating a Frozenset

x = frozenset([1, 2, 2, 3])

- frozenset() creates an immutable set.

- It automatically removes duplicate elements.

- The value of x becomes {1, 2, 3}.

- Unlike a normal set, a frozenset cannot be modified after creation.

2. Performing Set Union

x | {3, 4, 5}

- The | operator performs a union operation.

- It combines elements from both sets.

- Duplicate elements are automatically removed.

- Result: {1, 2, 3, 4, 5}.

3. Counting Unique Elements

len(x | {3, 4, 5})

- len() counts the total number of elements.

- The union contains 5 unique elements.

- Therefore, the output is 5.

Output

5
