Question 11 - Short Answer Type Questions (2/3 Marks each) - Chapter 10 Class 11 - Tuples and Dictionaries

Write the output of the following code   

A={10:100,20:200,30:3000,40:4000,50:5000} 
print A.items() 
print A.keys() 
print A.values() 

Answer:

The output of the code is:

[(10, 100), (20, 200), (30, 3000), (40, 4000), (50, 5000)] 

[10, 20, 30, 40, 50] 

[100, 200, 3000, 4000, 5000]

Explanation:

• The code creates a dictionary object named A in Python. 
• The code then uses three methods to access different aspects of the dictionary object: items(), keys(), and values(). 
• The items() method returns a list of tuples containing the key-value pairs in the dictionary. 
• For example, A.items() returns [(10, 100), (20, 200), (30, 3000), (40, 4000), (50, 5000)], which is a list of tuples containing the key-value pairs in A.
• The keys() method returns a list of the keys in the dictionary. For example, A.keys() returns [10, 20, 30, 40, 50], which is a list of the keys in A.
• The values() method returns a list of the values in the dictionary. For example, A.values() returns [100, 200, 3000, 4000, 5000], which is a list of the values in A.
• The code then prints the results of these methods using the print() function.

Therefore, the output of the code is:

[(10, 100), (20, 200), (30, 3000), (40, 4000), (50, 5000)] 

[10, 20, 30, 40, 50] 

[100, 200, 3000, 4000, 5000]
