Python Project #7: Caesar Cipher to Encrypt and Decrypt Data

Learn to create user-defined functions to take plain-text and scramble it using Caesar cipher. By the end of this tutorial, you will be able to create Caesar cipher that is able to handle upper case letters, lower case letters, and symbols. We will be able to encrypt plain-text provided by the user into cipher-text, as well as decrypt and get the original plain-text back from the cipher-text. For this tutorial, I will use slicing technique.
