Lesson Complete - The Quiz Loop | Upgrade PyQuiz — Control Flow

You finished the second lesson of Upgrade PyQuiz. The quiz now asks three questions per round, tracks a streak, and lets the player go again.

Here is the complete quiz.py:

QUESTIONS = [
    ("What is the type of the value 3.14?", "int", "str", "float", "bool", 3),
    ("What keyword defines a function in Python?", "for", "def", "if", "class", 2),
    ("What does print() do?", "Stores a value", "Returns a number", "Displays output", "Reads input", 3),
]
total = 3

while True:
    score = 0
    streak = 0
    print("=== Python Quiz ===")
    print()
    for text, o1, o2, o3, o4, correct in QUESTIONS:
        print(text)
        print()
        print(f"  1) {o1}")
        print(f"  2) {o2}")
        print(f"  3) {o3}")
        print(f"  4) {o4}")
        print()
        answer_text = input("Your answer (1-4): ")
        answer = int(answer_text)
        is_correct = answer == correct
        print()
        print(f"You answered: {answer}")
        if is_correct:
            score = score + 1
            streak = streak + 1
            print("Correct!")
            if streak >= 3:
                print(f"  Hot streak! ({streak} in a row)")
        else:
            streak = 0
            print(f"Wrong! The correct answer was option {correct}.")
    print(f"Score: {score}/{total}")
    if score == total:
        print("Perfect score!")
    elif score >= 2:
        print("Great job!")
    elif score >= 1:
        print("Not bad!")
    else:
        print("Keep practicing!")
    print()
    again = input("Play again? (y/n): ")
    if again != "y":
        break

print("Thanks for playing!")

What you added:

QUESTIONS list — stores all question data as tuples; adding a question means adding one line
for loop — iterates over QUESTIONS, unpacking each tuple into named variables
Score tracking — score counts correct answers, total tracks how many questions ran
elif chain — grades the final score (perfect, great, not bad, keep practicing)
Streak tracking — consecutive correct answers increment streak; a wrong answer resets it
while True + break — runs the quiz in a loop; the player controls when to stop

What's still missing: quiz.py is getting long. All the quiz logic is in one flat block inside the while loop. In the next lesson, you will extract it into named functions — ask_question, show_results, and run_quiz — so each piece has a clear purpose and can be reused independently.
