Notes

"""Imagine a publishing company that markets both book and compact disk versions of its works.
Create a class publication that stores the title (a string) and price (type float) of a publication.
From this class derive two classes: book, which adds a page count (type int), and CD,
which adds a playing time in minutes (type float). Each of these three classes should have
a getdata() function to get its data from the user at the keyboard, and a putdata() function
to display its data. Write a main() program to test the book and CD classes by
creating instances of them, asking the user to fill in data with getdata(),
and then displaying the data with putdata()"""

def get_data(self):
self.title=input("Enter the title:")
self.price=float(input("enter the price:"))

self.page=int(input("enter the page count:"))
