exercises exercises this exercise will use the facilities in the asyncio library to calculate set of factorial numbers the factorial of positive integer is the product of all positive integers less than or equal to for example note that the value of is create an application that will use the async and await keywords to calculate the factorials of set of numbers the factorial function should await for of second (using asyncio sleep( )each time round the loop used to calculate the factorial of number you can use with asyncio as_completed(or asyncio gather(to collect the results up you might also use list comprehension to create the list of calls to the factorial function the main function might look likedef main()print('main starting'asyncio run(calculate_factorials([ ])print('main done'if __name__ ='__main__'main(
