The exact instructions can vary slightly between courses, but the core task is usually this:
The assignment is a fantastic way to learn about data compression and the fundamentals of binary data. By mapping A-Z and space to unique 5-bit codes, you can create an efficient, custom encoder.
Here is a clean, working solution that fulfills the standard requirements for 8.3.8.
Your encoding function would then need to handle both uppercase and lowercase inputs (or convert everything to a single case) and properly encode the period. The decoding function would split the binary string into 6‑bit chunks and reverse‑lookup the corresponding character.
To crack the code, we need to understand the pattern. After analyzing the code, we discover that:
alphabet = "abcdefghijklmnopqrstuvwxyz " mapping = alphabet[i]: i+1 for i in range(len(alphabet)) reverse_mapping = v: k for k, v in mapping.items()
