I want to implement the algorithm using spaced repetition in python What are the approximate steps

Here are the approximate steps to implement the spaced repetition algorithm in Python:

1. Define the data structure to store the information about the flashcards, such as the question, answer, last review date, and the interval until the next review.

2. Load the flashcards data from a file or database into your program.

3. When the user starts the program, show them the first flashcard with the question and ask them to provide the answer.

4. Compare the user's answer with the correct answer and display the result.

5. Update the flashcard's last review date and the interval until the next review based on the user's performance.

6. Save the flashcards data back to the file or database.

7. Repeat steps 3 to 6 for the remaining flashcards in the deck.

8. When all the flashcards have been reviewed, calculate the next review date for each card based on its interval and the current date.

9. Save the updated flashcards data back to the file or database.

10. Repeat steps 3 to 9 at the next review date for each flashcard.

11. Provide options for the user to add new flashcards, delete existing ones, and adjust the review intervals.

12. Add error handling and appropriate messaging to inform the user about any issues or errors that occur during the program's execution
