# Simple Python program to generate nursing-themed flashcards and tests from pasted PDF text.
# This script assumes you paste the extracted text from your PDF (use tools like online PDF-to-text converters if needed).
# It processes the text, extracts key sentences/phrases, and creates flashcards in a Quizlet-like format (CSV for easy import).
# For tests, it generates multiple-choice questions based on the content.
# Nursing theme: Flashcards are formatted with categories like "Assessment," "Intervention," "Nursing Diagnosis," etc., to aid study.
