Create a flashcard system with CLI

Here’s a simple Python-based CLI flashcard system. It allows you to:

• Add flashcards (question + answer)

• Review flashcards

• Save/load flashcards from a file

python
CopyEdit
import json
import os

FLASHCARDS_FILE = "flashcards.json"

def load_flashcards():
    if os.path.exists(FLASHCARDS_FILE):
        with open(FLASHCARDS_FILE, "r") as f:
            return json.load(f)
    return {}

def save_flashcards(flashcards):
    with open(FLASHCARDS_FILE, "w") as f:
        json.dump(flashcards, f, indent=4)

def add_flashcard(flashcards):
    question = input("Enter question: ").strip()
    answer = input("Enter answer: ").strip()
    flashcards[question] = answer
    print("Flashcard added!")

def review_flashcards(flashcards):
    if not flashcards:
        print("No flashcards to review.")
        return
    for question, answer in flashcards.items():
        print(f"nQuestion: {question}")
        input("Press Enter to see the answer...")
        print(f"Answer: {answer}")
        input("Press Enter for next flashcard...")

def main():
    flashcards = load_flashcards()

    while True:
        print("nFlashcard System")
        print("1. Add flashcard")
        print("2. Review flashcards")
        print("3. Exit")

        choice = input("Choose an option: ").strip()

        if choice == "1":
            add_flashcard(flashcards)
            save_flashcards(flashcards)
        elif choice == "2":
            review_flashcards(flashcards)
        elif choice == "3":
            print("Goodbye!")
            break
        else:
            print("Invalid choice. Try again.")

if __name__ == "__main__":
    main()

You just run this script in your terminal. It saves flashcards in a JSON file locally and loads them automatically next time.
Want me to extend it with categories, quizzes, or spaced repetition?
