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.
The objective of this exercise is to write a program that takes a string of text and "encodes" it based on a rule you define. This is essentially the foundation of cryptography. You aren't just shifting letters (like a Caesar Cipher); you are mapping specific characters to entirely different values. The Logic: How Encoding Works 83 8 create your own encoding codehs answers
def encode(message):
result = []
for ch in message:
result.append(chr(ord(ch) ^ 42))
return ''.join(result)
Pick one you fully understand.
In the CodeHS interface, you typically enter these values into a table or dictionary. If writing the Python function for this logic, use a dictionary to map characters to their binary equivalents. 83 8: Create Your Own Encoding — A
