Question

Which of the following built-in function/method returns a dictionary?

• A. dict()
• B. keys()
• C. values()
• D. items()

Hint:

Use dict() to build a new dictionary,
and use keys(), values(), and items() to access parts of an existing one.

Answer 1

The Correct Option is A

The built-in dict() constructor in Python generates a new dictionary object. This constructor accepts key-value pairs or other mappings to form the dictionary. Methods like keys(), values(), and items() operate on an existing dictionary but do not create a new one. Specifically, keys() provides a view of the dictionary's keys, values() returns a view of its values, and items() returns a view of its key-value pairs as tuples. Only the dict() function is responsible for the actual creation and return of a dictionary object. Consequently, option (A) is the correct choice.
