Question 24:Find the output of the following program:

dictionary = {1:'1', 2:'2', 3:'3'}
del dictionary[1]
dictionary[1] = '10'
del dictionary[2]
print (len(dictionary) )

(A) 1
(B) 2
(C) 3
(D) 4

Answer: (B)
Explanation: The task of the ‘del’ function is to remove key-value pairs from a dictionary. Initially the size of the given dictionary was 3. Then the key value pair for key 1 is first removed and then added back with a new value. Then the key value pair for key 2 is removed. So, finally the size of the dictionary is 2.
