Flashcard App Project (code) in Python

Flashcard App in Python.

About the project: This app will present you with a series of flashcards containing a question on one side and an answer on the other.

It will keep track of your progress and allow you to study different topics.

You can easily add, remove, and edit the flashcards to create your own study sets.

Flashcard App:

This Python script provides a complete and interactive Flashcard App.

It has a menu-driven interface, allowing you to add new flashcards and then study them in a randomized order.

Your flashcards are saved to a JSON file, so they will be available the next time you run the app.
