OOP

OOP is object oriented programming and the principle itself is quite simple. You assign a class and create attributes and methods. However when this was implemented in real coding, I found it hard to unravel. It was confusing connecting attributes made in the class to methods in the class. It seemed that attributes and methods used the same variables and this made little sense as usually a function can only limit variable use within a function.

class QuizBrain:

def __init__(self, q_list):

self.question_number = 0

self.score = 0

self.question_list = q_list

def still_has_questions(self):

return self.question_number < len(self.question_list)

def next_question(self):

current_question = self.question_list[self.question_number]

self.question_number += 1

user_answer = input(f"Q.{self.question_number}: {current_question.text} (True/False): ")

self.check_answer(user_answer, current_question.answer)

def check_answer(self, user_answer, correct_answer):

if user_answer.lower() == correct_answer.lower():

self.score += 1

print("You got it right!")

else:

print("That's wrong.")

print(f"The correct answer was: {correct_answer}.")

print(f"Your current score is: {self.score}/{self.question_number}")

print("\n")

In this code in the init attributes, attribute question number and score were set at 0 to ensure they started off as such. Question lists were also made as an attribute. Later in the still_has_questions, the method used the attribute names made in the init attribute line.

Also in the next_question method, the current question was made using attributes from the init.

question_bank = []

for question in question_data:

question_text = question["question"]

question_answer = question["correct_answer"]

new_question = Question(question_text, question_answer)

question_bank.append(new_question)

quiz = QuizBrain(question_bank)

while quiz.still_has_questions():

quiz.next_question()

print("You've completed the quiz")

print(f"Your final score was: {quiz.score}/{quiz.question_number}")

I was confused how the rest of the methods were supplied with the needed input. Apparently, you have to mention it beforehand.

The way it is pointed out above is in the form of quiz = QuizBrain(q_list)
