# 1. Define your secret mapping # Each key is a normal letter, each value is the encoded version encoding_map = " a " : " 4 " , " b " : " 8 " , " e " : " 3 " , " l " : " 1 " , " o " : " 0 " , " s " : " 5 " , " t " : " 7 " def encode_message ( message ): encoded_result = " " # 2. Loop through every character in the user's message for char in message.lower(): # 3. Check if the character is in our dictionary if char in encoding_map: encoded_result += encoding_map[char] else : # If it's not in the dictionary, keep the original character encoded_result += char return encoded_result # 4. Get input and print the result user_input = input( " Enter a message to encode: " ) print( " Encoded message: " + encode_message(user_input)) Use code with caution.

Your custom encoding can be optimized for specific types of data. Why Is This Lesson Important? Use it to test your code and make adjustments as necessary
Ensure your encoding logic accounts for both uppercase and lowercase letters. Using .lower() in Python or checking both conditions in JavaScript ( 'a' vs 'A' ) prevents unhandled characters.
// 2. Build the reverse mapping for decoding. const DECODING = {}; for (let char in ENCODING) DECODING[ENCODING[char]] = char;
