Step-by-Step Code Explanation 1. Preventing Index Errors continue for the whole alphabet Use code with caution

Start by creating a dictionary that defines your cipher. Each key should be a lowercase letter, and each value should be the character you want to replace it with. # Example: A simple "Shift" cipher or random map encoding_map # ... continue for the whole alphabet Use code with caution. Copied to clipboard 2. Create the Encoding Function If the system expects Encoded message: [text] ,

Ensure your output text matches the CodeHS test cases precisely. If the system expects Encoded message: [text] , do not write Your secret code is: [text] .
