PLEASE DESCRIBE THE STEPS IN THE CODE! please.. (simple code) In this homework, the rail fence cipher is written in Python. We did implement this already in the class by appending letters sequentially to three different lists, which represented three rails. In this project, you are allowed to implement it in any other way. First step is to drop all the space characters inside the plain text. An easy way to implement it is to notice that the first rail...
