Question

(Analyze scores) Write a program that reads an unspecified number of scores and determines how many scores are above or equal to the average and how many scores are below the average. Enter a negative number to signify the end of the input. Assume that the maximum number of scores is 100.

Here is a sample run:Enter a new score or negative number to exit: 99.1Enter a new score or negative number to exit: 85.6Enter a new score or negative number to exit: -1Total scores entered: 2Average score: 92.35Number of scores above or equal to the average: 1Number of scores below the average: 1

Answer 1

#section 1

ls = []

while True:

score = float(input('Enter a New score or negative number to exit: '))

if score < 0:

break

else:

ls.append(score)

#section 2

average = sum(ls)/len(ls)

a = [num for num in ls if num >= average]

print('Total Scores Entered: ',len(ls))

print('Average score entered is: ',average)

print('Number of scores above average is: ',len(a))

print('Number of scores below average is:', len(ls)-len(a))

Step-by-step explanation:

The programming language used is python 3.

#section 1

In this section, an empty list is initialized to hold all the values that will be inputted.

A while loop created which prompts the user to enter an input until a negative value is entered. This while loop always evaluates to be true until a value less than 0 allows it to break.

Finally, all the scores are appended to the list.

#section 2

In this section the code gets the average by dividing the sum by the number of items in the list.

A new list 'a' is created to hold all the values that are greater than or equal to the average.

Finally, the results are printed to the screen.
