In the film, The Shawshank Redemption, how does Andy have hope and/or is there any other symbolism representing the significance of hope?I am just...

Andy never drops a hint of giving up during his long stint
in Shawshank Prison. He fights off "The Sisters," repeatedly, succumbing--but never
willingly--to their homosexual attacks. The two most obvious symbols of hope are the two
objects which best help him to eventually escape: the tiny rock hammer, which the warden
and guards assume is for hobby interest only; and the movie posters which hide the
entrance to his tunnel. His books and job as head librarian, which he inherits from
Brooks Hatlen, inspire him to keep the idea of eventual freedom alive, as does his
playing of The Marriage of Figaro, which lands him in solitary
confinement but gives him--and the other inmates--a few minutes of joyful
exhuberance.
