Before you write a single line of code, decide how your characters will transform. A common approach is to use a dictionary (in Python) or a series of conditional checks. a becomes 4 e becomes 3 i becomes 1 o becomes 0 s becomes 5 Step 2: The Core Logic

The objective is to create a program that takes a string of text from the user and "encodes" it by replacing specific characters with others. Unlike a simple Caesar Cipher (which shifts everything by a set number), this exercise encourages you to define your own unique rules—essentially building your own secret language. Step 1: Define Your Mapping

To encode a full string, you need to iterate through every character the user provides. to hold your encoded message. Loop through the input string character by character. Check each character against your rules. Append the result to your new string. Step 3: Example Implementation (Python)

CodeHS often checks for comments. Briefly explain what your specific encoding rule is at the top of your script. Why This Matters
