5.2.8 Average Test Score CodeHS Answers

The most common answer for the 5.2.8 Average Test Score CodeHS is:

total = 0

for i in range(3):
    next = int(input("Enter a test score: "))
    total = total + next
    
print("Average: " + str(total/3))

This code for calculating the average test score is almost correct, but there are a couple of improvements to be made for better clarity and accuracy:

1. The print statement for the average should be placed outside the loop, so it only prints once after all scores are entered and summed.
2. It’s good practice to use descriptive variable names. Instead of For3Scores and Average, names like score and total_score might be more appropriate.

Here’s the revised version of the code:

import random

# Initialize variables
roll_count = 0

while True:
    # Roll two dice
    die1 = random.randint(1, 6)
    die2 = random.randint(1, 6)
    roll_count += 1

    # Print the values rolled
    print(f"Rolled: {die1} {die2}")

    # Check for snake eyes (both dice are 1)
    if die1 == 1 and die2 == 1:
        break

# Output the total number of rolls
print(f"It took you {roll_count} rolls to get snake eyes.")

In this revised code:

• The loop iterates three times, each time asking for a score and adding it to total_score.
• The average is calculated as total_score / 3 and is printed after the loop completes. This ensures the average is only displayed once, after all the scores are entered.
• Descriptive variable names are used for better readability.
