Question 2:Find the output of the following program:
D = {1 : 1, 2 : '2', '1' : 1, '2' : 3
D['1'] = 2
print(D[D[D[str(D[1])]]]) 

                    
(A) 2 (B) 3 (C) ‘2’ (D) KeyError

Answer: (B)

Explanation: Simple key-value pair is used recursively, D[1] = 1, str(1) = ‘1’. So, D[str(D[1])] = D[‘1’] = 2, D[2] = ‘2’ and D[‘2’] = 3.
