How would you create a new empty set in Python?

• A. Using {}
• B. Using list()
• C. Using tuple()
• D. Using set()

Answer: (D)

A new empty set in Python is created by using the set() function. This is the definitive way to instantiate an empty set because the curly braces {} are actually interpreted as an empty dictionary when used alone.

The set() function specifically initializes a new set object, ensuring it is recognized as a set, which allows you to perform set-specific operations like unions, intersections, and variances later on.

Other options like list() and tuple() are designed for creating empty lists and tuples, respectively, and do not pertain to sets at all. Therefore, using set() is the accurate method for creating an empty set in Python.
