Initializing the book along with its covers

The create_book function creates a book record and its associated covers using data from the data dictionary. First, it extracts the list of covers from the dictionary, then creates a Book object, and subsequently creates BookCover objects linked to the newly created book. Review the code: check the syntax, correctness of data passing, optimization possibilities, and potential errors.

def create_book(data: dict):
    cover_list: list[dict] = data.pop('covers')
    new_book = Book.objects.create(**data)
    for cover in cover_list:
        BookCover.objects.create(**cover, book_id=new_book.id)
