The purpose of this assignment is to reinforce Python concepts. Develop a Python program. Define a class in Python and use it to create an object and display its components. Define a Book class where a book contains the following components (attributes):

* an author

* a title

* a number of pages

This class includes several methods: to change the values of these attributes, and to display their values. Separately, the main program must:

request the corresponding data from input and create a book object.

invoke a method to change the value of one of its attributes

invoke a method to that displays the value of each attribute.
