8.3 8 Create Your Own Encoding Codehs Answers [repack] -

The 8.3.8 assignment in CodeHS challenges students to go beyond standard encoding methods (like ASCII or Morse code) and design their own or mapping system.

You need to create a function that takes a string and replaces each letter with a corresponding value from a "code" dictionary. If a character isn’t in your dictionary (like a space or punctuation), you typically keep it as is. Sample Solution (Python) 8.3 8 create your own encoding codehs answers

To keep the example simple, we will focus on A–Z and space. Sample Solution (Python) To keep the example simple,

using this system to test it out. Would you like to see how a word like looks in your new code? def encode(message): """ Encodes a message by shifting

def encode(message): """ Encodes a message by shifting letters forward by 1 and swapping case. """ encoded_message = "" for char in message: # Check if the character is a letter if 'a' <= char <= 'z' or 'A' <= char <= 'Z': # Convert to character code, shift, swap case # This is a simple example; you can make this more complex! new_char = chr(ord(char) + 1) encoded_message += new_char else: # Keep non-letters as they are encoded_message += char return encoded_message def decode(encoded_message): """ Decodes the message by reversing the shift. """ decoded_message = "" for char in encoded_message: if 'a' <= char <= 'z' or 'A' <= char <= 'Z': new_char = chr(ord(char) - 1) decoded_message += new_char else: decoded_message += char return decoded_message # Main Program user_input = input("Enter a message to encode: ") encoded = encode(user_input) print("Encoded:", encoded) print("Decoded:", decode(encoded)) Use code with caution. Explanation of the Code

How to transition from this exercise to using .

def main(): # Demonstration required by CodeHS original = "Hello World" print("Original:", original) encoded = encode(original) print("Encoded: ", encoded) decoded = decode(encoded) print("Decoded: ", decoded)
