Polybius Square Encryption in Python

Introduction

In this project, you will learn how to implement the Polybius square encryption algorithm. The Polybius square is a 5x5 grid that maps each letter of the English alphabet to a pair of coordinates. By encrypting text using this method, you can create a coded message that can only be decrypted by someone with knowledge of the Polybius square.

## Example 1
text = "tynam"; encryption_text = "4454331132"
## Example 2
text = "tynam123"; encryption_text = "4454331132123"
## Example 3
text = "TYnam"; encryption_text = "4454331132"
## Example 4
text = None; encryption_text = None
