Specifications
Create a Random IntList class that inherits the list class. This class should allow a programmer to
create a list of random integers from 1 100 by writing a single line of code. For example, a
programmer should be able to create a custom list that stores 12 random integers with this line of
code:
●
●
int_list = RandomIntList (12)
To do that, you can use the self keyword to access the list superclass like this:
self.append (rand_int)
The RandomIntList class should contain methods or properties for getting the count, average, and
total of the numbers in the list. In addition, it should contain a
str method for displaying a
comma-separated list of integers as shown above.
The program should use the RandomIntList class to generate the list of random integers, display
the list, and get the summary data (count, total, and average).
The program should make sure the integer entered by the user is valid.

Coffee Shop or it should print the message "Sorry, we do not carry that.". 6 NUM_ITEMS = 5 # Named constant 8 # Initialized list of add-ins 9 addIns = ["Cream", "Cinnamon", "Chocolate", "Amarett "Whiskey"] Read the problem description carefully before you begin. The data file provided for this lab includes the necessary input statements.

N should be a dynamic number entered by the user. Sample output: How many numbers would you like to enter?: 5 Enter a number: 34 Enter a number: 67 Enter a number: 23 Enter a number: 90 Enter a number: 12 The list is: [12, 67,23, 90, 34]arrow_forwardThe function sum_evens in python takes a list of integers and returns the sum of all the even integers in the list.

You program should first prompt the user to enter how many numbers that will specify. The program should then scan for each number, separated by a newline. You should calculate the average value and return the number from the list which is furthest away from this average (to 2dp). Try using dynamic memory functions to store the incoming array of numbers on the heap.
