🧠 Quiz Game

A multiple-choice quiz that scores itself — questions stored as a list of dictionaries, presented one at a time, with a running score tallied and reported as a percentage at the end.

🎮 What We're Building

A quiz that presents a series of multiple-choice questions, checks each answer as it's given, and prints a final score out of the total, plus a percentage.

Step 1: Representing Questions

questions = [
    {
        "question": "What does CPU stand for?",
        "choices": ["Central Processing Unit", "Computer Personal Unit", "Central Program Utility"],
        "answer": "A"
    },
    {
        "question": "Which keyword defines a function in Python?",
        "choices": ["func", "def", "function"],
        "answer": "B"
    },
]
        

Each question is a dict (Course 1, Chapter 7) with three keys; the whole quiz is a list of these dicts, reusing exactly the "list of dicts" shape Chapter 4's to-do app used for tasks. "answer" stores the correct choice's letter, not its full text — comparing letters is simpler than comparing whole sentences.

Step 2: Presenting a Question

letters = "ABC"

def ask_question(q):
    print(q["question"])
    for i, choice in enumerate(q["choices"]):
        print(f"  {letters[i]}. {choice}")
        

enumerate (Course 1, Chapter 4) pairs each choice with its position; letters[i] reuses plain string indexing (Course 1, Chapter 5) to turn that position into the matching letter — letters[0] is "A", letters[1] is "B", and so on.

Step 3: Checking Answers & Scoring

def check_answer(q, user_answer):
    return user_answer.strip().upper() == q["answer"]
        

⚠ Normalize User Input Before Comparing

A player typing "b", " B", or "B " should all count as correct — but "b" == "B" is False (Course 1's string comparisons are case-sensitive), and stray whitespace from pressing Enter carelessly breaks an exact match too. .strip() (Course 1, Chapter 5) removes surrounding whitespace, .upper() normalizes case — chaining both before comparing is standard practice for any free-text-ish user input.

Step 4: The Quiz Loop & Final Score

score = 0

for q in questions:
    ask_question(q)
    user_answer = input("Your answer: ")
    if check_answer(q, user_answer):
        print("Correct!\n")
        score += 1
    else:
        print(f"Nope — the answer was {q['answer']}.\n")

percentage = (score / len(questions)) * 100
print(f"Final score: {score}/{len(questions)} ({percentage:.0f}%)")
        

score is the accumulator pattern one more time (Course 1, Chapter 4) — incremented once per correct answer, read only after the loop finishes. score / len(questions) reuses the average-style division from earlier chapters, scaled to a percentage and formatted to a whole number with :.0f (Course 1, Chapter 5).

🏁 The Complete Quiz Game

questions = [
    {
        "question": "What does CPU stand for?",
        "choices": ["Central Processing Unit", "Computer Personal Unit", "Central Program Utility"],
        "answer": "A"
    },
    {
        "question": "Which keyword defines a function in Python?",
        "choices": ["func", "def", "function"],
        "answer": "B"
    },
]

letters = "ABC"

def ask_question(q):
    print(q["question"])
    for i, choice in enumerate(q["choices"]):
        print(f"  {letters[i]}. {choice}")

def check_answer(q, user_answer):
    return user_answer.strip().upper() == q["answer"]

score = 0

for q in questions:
    ask_question(q)
    user_answer = input("Your answer: ")
    if check_answer(q, user_answer):
        print("Correct!\n")
        score += 1
    else:
        print(f"Nope — the answer was {q['answer']}.\n")

percentage = (score / len(questions)) * 100
print(f"Final score: {score}/{len(questions)} ({percentage:.0f}%)")
        

List of dicts

Each question is a dict; the quiz is a list of them — same shape as Chapter 4's tasks.

enumerate + string indexing

Turns each choice's position into a letter label (A, B, C...).

Normalized comparison

.strip().upper() before comparing user input to the stored answer.

Scoring

An accumulator, converted to a percentage at the end.

🚀 Extend This Project

Try these on your own:

Use random.shuffle(questions) so the question order is different each playthrough.
Load questions from an external JSON file (Course 2, Chapter 7) instead of hardcoding them, so new quizzes don't require editing the code.
Add a category field to each question, and let the player choose a category before starting.
Track and display which specific questions were missed at the end, not just the final score.
