This step is more interesting. You will need to walk through the binary string from left to right, matching patterns against your code table until you identify a valid code, then append the corresponding character to the result, and continue with the remaining bits.
Before shifting, reverse the entire message.

The exercise on CodeHS challenges you to apply everything you have learned about binary and character encoding in a creative, hands‑on way. Whether you choose a straightforward fixed‑width encoding or a more efficient variable‑width design, the key is to define clear mappings and implement both encoding and decoding functions carefully.
possible values). Using fewer than 5 bits won't provide enough unique combinations, and using more than 5 bits is less efficient. Step-by-Step Solution Assign Bits : Set your "Bits in Encoding" to Map the Characters
: Takes the integer value, adds 1 (shifts it), and turns it back into a character. Is your code failing a in the autograder
Mastering CodeHS 8.3.8: Create Your Own Encoding Data encoding is the backbone of modern computer science. It transforms human-readable text into secure, efficient, or compressed formats. In the CodeHS JavaScript and Python curriculums, Section 8.3.8 challenges you to build your own custom encoding program.
result = "" for ch in text.upper(): if ch == " ": result += "27" else if ch == ".": result += "28" else: result += format(ord(ch) - ord('A') + 1, width=2, pad='0') return result
If you want this tailored to a specific allowed character set or language (e.g., include lowercase, digits, or emojis), tell me which and I’ll adapt the scheme and examples. Before shifting, reverse the entire message
: Use .lower() on your input so your dictionary doesn't need both "A" and "a".
CodeHS is the culmination of a series of exercises that introduce the fundamental ways computers represent text as binary data. The module typically covers:
def encode_message(message): """ Takes a string and encodes it by shifting every character by a fixed number of positions in the ASCII table. """ encoded_result = "" # Loop through every character in the original message for character in message: # Shift the ASCII value of the character by 3 shifted_ascii = ord(character) + 3 # Convert the new ASCII value back into a character new_character = chr(shifted_ascii) # Append the new character to our result string encoded_result += new_character return encoded_result def main(): print("--- Custom Text Encoder ---") # Prompt the user for input user_input = input("Enter a message to encode: ") # Process the message through the encoding function secret_code = encode_message(user_input) # Output the result print("Encoded message: " + secret_code) # Execute the program if __name__ == "__main__": main() Use code with caution.
