EASY Rail fence cipher Python 3 (Encryption Algorithm)

This video covers the encryption side of the Rail fence cipher algorithm. I provide a brief overview of what the program is doing and how it works, such that you may be able to optimise the code or apply certain aspects of it to your own version. I will upload the Decryption algorithm soon. ALLTECH video: https://youtu.be/L5Dsxtl4iIo Disclaimer: I am by no means an expert. I am relatively new to Python, most of my experience is in C.
