The title of the exercise suggests you should "create your own." While using standard ASCII ( ord ) is the most common way to complete the assignment, you could technically create a "custom" encoding by shifting the numbers.
ALPHABET = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 .,?!'\"-_~@#$%^&*+=/\\|" def encode83(s): block = 8 pad = '~' res = "" for i in range(0, len(s), block): chunk = s[i:i+block] chunk += pad * (block - len(chunk)) for ch in chunk: if ch not in ALPHABET: raise ValueError("Unsupported character") res += ch # or map to index and pack numerically return res 83 8 create your own encoding codehs answers exclusive
The 83-8 encoding is an educational, reversible scheme suited for classroom assignments. It demonstrates mapping, padding, block processing, and simple error handling. The title of the exercise suggests you should
If your "8.3.8" assignment is actually the coding exercise, you need to create a get_index and get_letter function. The core logic for replacing a character at a specific index in Python is: If your "8
This paper defines a simple custom encoding scheme called "83-8" designed for educational programming exercises. It describes the encoding rules, provides encoding/decoding algorithms with pseudocode, gives worked examples, explains edge cases and error handling, and includes sample CodeHS-style answers and test cases.
