Program written in Python to build flashcards, using classes in Python

Generally speaking, Flashcard is a learning tool that consists of a small card or piece of paper with information printed on one side. These are often used to help memorize and learn facts, vocabulary, definitions, equations, or any other information that can be presented in a question and answer format.

As technology advances, flashcards are also converted into digital formats such as mobile apps and online platforms that offer additional features such as multimedia content, spaced repetition algorithms, and progress tracking.

There are multiple ways to build flashcards in Python, let’s cover them one by one.

Flashcard as a class attribute

In Python, the class attribute is a variable bound to a class rather than an instance of the class. It is shared among all instances of the class and can be accessed and modified using the class name or instances of the class.

is:

Example

In this example, we define the flashcards as class properties, and each flashcard object will have properties that store the questions and answers. We can define methods in the class to display the question, receive the answer entered by the user, and check if the answer is correct.

class Flashcard:
   def __init__(self, question, answer):
      self.question = question
      self.answer = answer
   def display_question(self):
      print("Question:", self.question)
   def get_user_answer(self):
      return input("Your answer: ")
   def check_answer(self, user_answer):
      return user_answer == self.answer
card = Flashcard("What is the capital of India?", "Delhi")
card.display_question()
user_answer = card.get_user_answer()
is_correct = card.check_answer(user_answer)
print("Your answer is correct:", is_correct)

Output

Question: What is the capital of India?
Your answer: Delhi
Your answer is correct: True

Flashcard as an instance of Flashcard class

In this approach, each flashcard is represented as a dictionary where questions and answers are stored as key-value pairs.

The Chinese translation of

Example

is:

Example

In this example, each flashcard is represented as a dictionary in the Flashcard class. The __init__ method initializes the flashcard dictionary with the question and answer as key-value pairs. We can access each flashcard question and answer using the corresponding key.

class Flashcard:
   def __init__(self, question, answer):
      self.flashcard = {"question": question, "answer": answer}
flashcard1 = Flashcard("What is the capital of France?", "Paris")
flashcard2 = Flashcard("Who painted the Mona Lisa?", "Leonardo da Vinci")
print(flashcard1.flashcard["question"])
print(flashcard1.flashcard["answer"])
print(flashcard2.flashcard["question"])
print(flashcard2.flashcard["answer"])

Output

What is the capital of France?
Paris
Who painted the Mona Lisa?
Leonardo da Vinci

Flashcard as a class with methods

In this approach, each flashcard is represented as an instance of the Flashcard class, which also contains methods for displaying questions and answers.

The Chinese translation of

Example

is:

Example

In this example, each flashcard is represented as an instance of the Flashcard class. The __init__ method initializes the question and answer properties of each flashcard. This class also contains the display_question() and display_answer() methods for displaying the question and answer for each flashcard.

class Flashcard:
   def __init__(self, question, answer):
      self.question = question
      self.answer = answer
   def display_question(self):
      print(self.question)
   def display_answer(self):
      print(self.answer)
flashcard1 = Flashcard("What is the capital of France?", "Paris")
flashcard2 = Flashcard("Who painted the Mona Lisa?", "Leonardo da Vinci")
flashcard1.display_question()
flashcard1.display_answer()
flashcard2.display_question()
flashcard2.display_answer()

Output

What is the capital of France?
Paris	
Who painted the Mona Lisa?
Leonardo da Vinci
