Ask questions in turn with run.
Playing the quiz
You add a play method to the Quiz class to print every question to the screen. The method body loops over for q in self.questions: and shows the text with print(q.text).
This simple play lists the questions without waiting for input. Later we'll add answer comparison with check_answer. For now the goal is to show questions in order; scoring comes in the next lesson.
Showing questions in order
During play you may also want to show the order of each question. Using enumerate(self.questions, start=1) gives you both the index and the question. So the output looks like Question 1: ..., Question 2: ....
You format with an f-string: f"Question {i}: {q.text}". Here i is the index, q.text is the question text. This makes the output testable and deterministic; each run gives the same result.
Practice Add the play method
Add a method def play(self): to the Quiz class above. Its body should have for i, q in enumerate(self.questions, start=1): and print(f"Question {i}: {q.text}"). Then create a quiz, add two questions (text="Capital?" and text="2x2?") and call quiz.play().
Starter code
from dataclasses import dataclass, field
@dataclass
class Question:
text: str = ""
answer: str = ""
@dataclass
class Quiz:
questions: list = field(default_factory=list)
def add_question(self, q):
self.questions.append(q)
# Add a play method to the Quiz class
# Create a quiz, add two questions and call playSample solution
from dataclasses import dataclass, field
@dataclass
class Question:
text: str = ""
answer: str = ""
@dataclass
class Quiz:
questions: list = field(default_factory=list)
def add_question(self, q):
self.questions.append(q)
def play(self):
for i, q in enumerate(self.questions, start=1):
print(f"Question {i}: {q.text}")
quiz = Quiz()
quiz.add_question(Question(text="Capital?", answer="Ankara"))
quiz.add_question(Question(text="2x2?", answer="4"))
quiz.play()Expected output
Question 1: Capital? Question 2: 2x2?

1 What does the play method return?
- Only prints text, returns nothing Correct answer
- The correct answers
- A list
- The total score
Explanation: The play method uses print.
2 Match the play parts
| Term | Meaning |
|---|---|
for q in self.questions |
Loop |
enumerate(...) |
Index |
print(q.text) |
Print text |
f"Question {i}: ..." |
Formatted output |
3 Complete the play method body
def play(self):
for i, q in enumerate(self.questions, start=1):
print(f"Question {____}: {q.text}") def play(self):
for i, q in enumerate(self.questions, start=1):
print(f"Question {i}: {q.text}")Explanation: The index is in the i variable.
