Introduction

Flashcards are a great way to enhance your memory retention. A flashcard typically has a question or prompt on one side and an answer on the other. The flashcard app we’re going to create will allow you to input questions and answers, review them, and track your progress as you learn new topics.

Objective

The objective of this program is to create a simple flashcard app in Python where users can add, view, and quiz themselves on flashcards. The application will:

• Allow users to create flashcards with a question and answer.
• Quiz users by showing questions and waiting for their answers.
• Provide feedback on the correctness of answers.
• Track the user’s progress as they go through the flashcards.

Python Code


# Flashcard App for Studying

class Flashcard:
def __init__(self, question, answer):
self.question = question
self.answer = answer

class FlashcardApp:
def __init__(self):
self.flashcards = []

def add_flashcard(self, question, answer):
flashcard = Flashcard(question, answer)
self.flashcards.append(flashcard)

def quiz(self):
correct = 0
for flashcard in self.flashcards:
print(f”Question: {flashcard.question}”)
user_answer = input(“Your answer: “)
if user_answer.lower() == flashcard.answer.lower():
print(“Correct!\n”)
correct += 1
else:
print(f”Incorrect! The correct answer is: {flashcard.answer}\n”)
print(f”You got {correct} out of {len(self.flashcards)} correct.”)

def display_flashcards(self):
if not self.flashcards:
print(“No flashcards available.”)
for flashcard in self.flashcards:
print(f”Question: {flashcard.question} | Answer: {flashcard.answer}\n”)

def main():
app = FlashcardApp()

while True:
print(“Flashcard App Menu:”)
print(“1. Add Flashcard”)
print(“2. Quiz Yourself”)
print(“3. View All Flashcards”)
print(“4. Exit”)

choice = input(“Enter your choice: “)

if choice == “1”:
question = input(“Enter the question: “)
answer = input(“Enter the answer: “)
app.add_flashcard(question, answer)
elif choice == “2”:
app.quiz()
elif choice == “3”:
app.display_flashcards()
elif choice == “4”:
print(“Thank you for using the Flashcard App!”)
break
else:
print(“Invalid choice, please try again.”)

if __name__ == “__main__”:
main()

Explanation of Program Structure

The program consists of the following key components:

• Flashcard Class: This class stores a question and its corresponding answer. It is used to create individual flashcards.
• FlashcardApp Class: This class manages the flashcards. It includes methods to add flashcards, quiz the user, and display all flashcards.
• Main Function: The main function is the entry point of the program. It provides a simple menu interface that allows users to interact with the app, add flashcards, take quizzes, or view existing flashcards.

How to Run the Program

To run this program, follow these steps:

1. Ensure you have Python 3.x installed on your computer.
2. Copy the Python code into a text editor and save it with a .py extension (e.g., flashcard_app.py).
3. Open a terminal (or command prompt) and navigate to the folder where the .py file is saved.
4. Run the program by typing python flashcard_app.py and pressing Enter.
5. The program will prompt you with a menu where you can choose to add flashcards, take a quiz, or view existing flashcards.
