Question 6 - MCQ Questions (1 Mark each) - Chapter 10 Class 11 - Tuples and Dictionaries

Predict the output of the following code if

mydict = {‘a’:23,'b': '78',’c’ :89, ‘d’:36}
>>>del mydict[‘c’]
>>>print mydict

(a) {‘a’:23,'b': '78',’c’ :89,‘d’:36}

(b) {‘a’:23,'b': '78',‘d’:36}

(c) {‘a’:23,'b': '78',89, ‘d’:36}

(d) {‘a’:23,'b': '78',’d’ :89, ‘e’:36}

Answer:

• The code uses the del statement to delete a key-value pair from a dictionary object in Python. 
• del mydict[‘c’] means that the key ‘c’ and its associated value 89 are removed from the dictionary object named mydict.
• The print statement prints the contents of the dictionary object to the standard output. 

Therefore, the output of the code is {‘a’: 23, ‘b’: ‘78’, ‘d’: 36} , which shows that the key ‘c’ and its value 89 are no longer present in the dictionary object named mydict.

So, the correct answer is (b) {‘a’:23,‘b’: ‘78’,‘d’:36}.
