I want to be able to open up an image file and extra the hexadecimal values byte-by-byte. I have no idea how to do this and googling "python byte editing" and "python byte array" didn't come up with anything, surprisingly. Can someone point me towards the library i need to use, specific methods i can google, or tutorials/guides?
