24 / 35Tuples and SetsMediumPython Basics

Predict the output of the following code that demonstrates set operations and membership testing?

set_a = {1, 2, 3, 4}
set_b = {3, 4, 5, 6}
print(set_a & set_b)

  1. {3, 4}

  2. {1, 2, 5, 6}

  3. {1, 2, 3, 4, 5, 6}

  4. Error: cannot use & operator on sets

Show answer & explanation

Correct answer

{3, 4}

Explanation

The `&` operator performs intersection, returning only elements present in both sets, which are {3, 4}.
