Question
Which of the following create an empty set?
A. s={}
B. s=[]
C. s=set([''])
D. s=set()
E. None of the above
Solution
To determine which options create an empty set, let's evaluate each option:
-
Option A:
s={}- This creates an empty dictionary, not an empty set.
-
Option B:
s=[]- This creates an empty list, not an empty set.
-
Option C:
s=set([''])- This creates a set with one element, which is an empty string. Hence, it is not an empty set.
-
Option D:
s=set()- This correctly creates an empty set.
-
Option E:
None of the above- Since option D creates an empty set, this choice is also incorrect.
Final Answer
The correct answer is D. s=set(), which creates an empty set.
