Plan the program

A program is easier to read when each idea has enough room. First describe the goal, then test one small part at a time.

Use names that explain the value, such as total_score or current_level.

Try the loop

• Start with a short list of values.
• Print one result before adding more logic.
• Check the output after every change.

scores = [3, 5, 8]
total_score = 0

for score in scores:
    total_score += score

print(total_score)
