If a={5,6,7}, what happens when a.add(5) is executed? a) a={5,5,6,7} b) a={5,6,7} c) Error as there is no add function for set data type d) Error as 5 already exists in the set
Answer: b Explanation: There exists add method for set data type. However 5 isn’t added again as set consists of only non-duplicate elements and 5 already exists in the set. Execute in python shell to verify.
