83 8: Create Your Own Encoding — A Step-by-Step Editorial

Encoding is everywhere: in secret messages, data compression, and the hidden rules that let computers talk. This editorial walks you through designing your own encoding system—clear, creative, and practical—so you can build a custom cipher or data-encoding scheme for learning, games, or class projects like CodeHS assignments.

Part 4: Decoding Function

def decode_message(binary_string): # Assuming a fixed bit length of 5 (based on our dictionary) bit_length = 5 text_output = "" 83 8 create your own encoding codehs answers

# Loop through the string in chunks of 5
for i in range(0, len(binary_string), bit_length):
    chunk = binary_string[i : i + bit_length]
if chunk in my_decoder:
        text_output += my_decoder[chunk]
    else:
        text_output += "?"
return text_output

The Goal

The goal is not just to get a passing grade, but to understand the fundamental concept of character encoding (similar to ASCII, UTF-8, or Base64) but on a smaller, custom scale. 83 8: Create Your Own Encoding — A

3. Reversed Keyboard Row

var encodingMap = 
    'a': 'q', 'b': 'w', 'c': 'e', 'd': 'r', 'e': 't',
    'f': 'y', 'g': 'u', 'h': 'i', 'i': 'o', 'j': 'p',
    // ... complete the mapping
;

Decoding the Message

To decode the message, we can use a similar function with the inverse shift: The Goal The goal is not just to

def decode_message(encoded_message, shift):
    return encode_message(encoded_message, -shift)
# Example usage
decoded = decode_message(encoded, shift)
print(f"Decoded message: decoded")

Understanding Encoding Basics

Encoding is the process of converting data or messages into a coded form to ensure confidentiality, integrity, or efficient transmission. There are various encoding techniques, including:

We need to reverse the dictionary to look up letters based on binary strings.

my_decoder = {} for key, value in my_encoding.items(): my_decoder[value] = key
