According to the search results, Peter Pettigrew met his end in different ways in the books and movies. In the book, Harry Potter and the Deathly Hallows, Peter Pettigrew hesitated to choke Harry, and the enchanted hand that Voldemort gave him turned on him and strangled him to death. In the movie, Harry Potter and the Deathly Hallows Part 1, Pettigrew was sent by Dobby to check on Harry, Ron, and Hermione, and he was hit with a spell by Dobby from the back, muttering a soft “ow” as he falls face-first. It almost makes it ambiguous as to whether or not Pettigrew dies, except that the character never appears in the movies following the fall.
