 This lab is a warm-up for the next assignment. We will learn to build a multi-threaded application. You will write a function that will simulate a long task. You will call the first method a number of times sequentially and record the time it takes to complete. They will call the first method again but in a threaded manner and time, the execution and then compare the two times. Description Create three functions:1.Create a function to the following:a.Take a string argument (name).b.Create a loop that will run 100 000 times. In this loop, the program will sleep 0.0001 seconds.c. After the completion of the loop, prints its name and a brief message.2.Create a second function to do the following:a. Takes a number argument (times to execute the loop).b.Store the current time. c.Call the function in step 1 the required number of times (sequentially).d.Check the elapsed time after the above calls are complete. e. Print the results as well as a brief message.

Design a 'book' class with title, author,publisher, price and author's royalty as instance variables. Provide getter and setter properties for all variables. Also define a method royalty() to calculate royalty amount author can expect to receive the following royalties :10% of the retail price on the first 500 copies ;12.5% for the next, 1000 copies sold, then 15% for all further other copies sold.

Then design a new 'ebook' class inherited from 'book'class.Add ebook format (EPUB, PDF, MOBI etc) and additional instance variable in inherited class.

Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.

Now add a function named clear_screen that uses a combination of the functions nine_lines, three_lines, and new_line (provided below) to print a total of twenty-five lines. The last line of your program should call first nine_lines and then the clear_screen function.

The function three_lines and new_line are defined below so that you can see nested function calls. Also, to make counting “blank” lines visually easier, the print command inside new_line will print a dot at the beginning of the line:

def new_line():

  print('.')

def three_lines():

  new_line()

  new_line()

  new_line()

Pass your marks of CA-1, CA-2, and CA-3, of course, INT102 to the function with header high

(float, float, float). Write a function that should return the highest CA mark
