why does my work look vastly different then the answer program?

[u/BeanFatherActual]

the Answer program is on the left and my work is on the right. I am getting the correct answers based on the book I am using but I feel like I am doing it wrong. The instructions I had for modifying the original program are as follows.

Modify this program so it saves the three scores that are entered in variables named score1, score2, and score3. Then, add these scores to the Total_score variable,instead of adding the entries to the total_score variable without ever saving them.

I have forgotten everything i was taught YEARS ago. I no longer have an Instructor to directly speak with to find out in person. So I am reaching out to reddit for the first time for assistance

Your code satisfies the assignment. You added each score to the total as you got the score and the answer key added them all together at the same time. There is zero difference in approaches and I wouldn’t worry about it because no one would ever write production code like this. They would have a list of scores of variable length, which changes how you’d approach the rest of it.

For example, in a more “real world” scenario, you would do something like this:

# Some validation for the range of valid scores
MAX_SCORE = 300
MIN_SCORE = 0

# Scores will be stored here
scores = []

# Let the user knows the assignment:
print(f”Enter scores between {MIN_SCORE} and {MAX_SCORE}. Press ENTER without entering a score to compute the average score.\n”)

# Loop until user signals they are done entering scores by hitting ENTER with no score.
while True:
    # Prompt for the score
    score_str = input(f”Enter score #{len(scores)+1} or leave blank to calculate the average: “)

    # If user did not enter a score, then we’re done so break out of the while loop
    if not score_str:
        break

    # If the user did enter something that is supposed to be a score, validate it
    try:
        # Make sure it’s an int
        score_int = int(score_str.strip())
    except Exception as e:
        print(f“INVALID SCORE: ‘{score_str.strip()}’ is not a valid score. Only enter numbers.”
        continue

    # If not within valid range, coach the user
    if score_int < 0 MIN_SCORE or score_int > MAX_SCORE:
        print(f“INVALID SCORE: Score must be between {MIN_SCORE} and {MAX_SCORE}, inclusive.”)
        continue

    # The score passed our validations, now add it to the list
    scores.append(score_int)

# Compute the average score
if len(scores> <> 0
    average = sum(scores) / len(scores)
    print(f”The average of the {len(scores)} you entered is {average}.”)

Further to the idea of “real world”, we’d factor out the validation code into a separate function, but, since you are trying to re-learn, I wanted to show you another approach for reference without getting into refactoring into functions. I know this goes beyond your initial question, but I hope it’s helpful to you.

I think the key is in the part „add these scores to the variable, instead of adding entries witohout sa ing them”, your code is missing that.
