  assert store_books([('The Hobbit', 'J.R.R. Tolkien', 295), ('The Catcher in the Rye', 'J.D. Salinger', 223)]) == [
    {'title': 'The Hobbit', 'author': 'J.R.R. Tolkien', 'pages': 295},
    {'title': 'The Catcher in the Rye', 'author': 'J.D. Salinger', 'pages': 223},
  ]
  assert store_books([]) == []
output: def store_books(books):
      return [{'title': title, 'author': author, 'pages': pages} for title, author, pages in books]
