 Question 16(CO 4 and 5) Create a program that will read in a list of test scores from the user and add them to a list. Ask the user in between each score if they want to continue (y/n). Display all of the scores entered and the total score at the end.

Using the code below, put the code in the proper order

SAMPLE OUTPUT:

Welcome to the Test Score Program

Add score:          88.45

Do you want to continue? y or n:              y

Add score:          91.2

Do you want to continue? y or n:              y

Add score:          77.22

Do you want to continue? y or n:              n

The scores were: [88.45, 91.2, 77.22]

Total score:         256.87

Specifications:

The program should accept decimal entries like 52.31 and 15.5.

Assume the user will enter valid data.

The program should round the results to a maximum of two decimal places.

Question 17(CO 4 and 6) Create a program with a function named flipCoin that will flip a coin as many times as the user asks. The flipCoin function should return “heads” or “tails”. The program should continue while the user presses Y. 

SAMPLE OUTPUT:

How many times do you want to flip a coin? 5

You got:  tails

You got:  tails

You got:  tails

You got:  tails

You got:  heads

To continue press Y:  Y

How many times do you want to flip a coin? 3

You got:  heads

You got:  tails

You got:  tails

To continue press Y:  N

SPECIFICATIONS:

You will need to import random in your code

The code to generate a number from 1 to the input sides is: flip = random.randint(1,2)

Use the .upper() command to check upper and lowercase input example: cont = input(“To continue press Y:  “).upper()

Using the code below, select the proper sequence of the code to produce the sample output shown.
