# Introduction In this project, you will learn how to implement a simple encryption and decryption algorithm called "Clear Code Encryption". This encryption method was used in China's early telegraph communication system during the late Qing Dynasty. ## 👀 Preview ```Python # Example 1 numb = 1530; encryption_text = "0383" # Example 2 numb = 0; encryption_text = "9853" # Example 3 numb = 12345; encryption_text = None ``` ## 🎯 Tasks In this project, you will learn: - How to understand the encryption method and its underlying principles - How to implement the `plain_code_encryption(numb)` function to perform the encryption - How to test the encryption function with various inputs - How to handle user input and call the encryption function ## 🏆 Achievements After completing this project, you will be able to: - Explain the "Clear Code Encryption" method and its historical context - Implement a basic encryption and decryption algorithm using Python - Test and validate the encryption function with different input scenarios - Integrate user input and output into the encryption script
