Unlike the classic Caesar Cipher (which simply shifts letters by a fixed numeric value), a custom encoding algorithm can combine multiple rules: Replacing specific vowels with symbols or numbers. Reversing string components. Inserting "noise" characters at specific intervals. Manipulating character codes (ASCII/Unicode values).
The basic ASCII shift code provided above shifts spaces too (a space ' ' has an ASCII value of 32, which shifts to 35, becoming # ). If your specific CodeHS prompt requires spaces to remain unchanged, add an if statement to check for spaces before shifting.
In this basic implementation, 'z' will shift into the next ASCII character ('{'). If your assignment requires 'z' to wrap around to 'a', you would need to add a specific check: 8.3 8 create your own encoding codehs answers

Starting with an empty string ( encodedText = "" ) and adding to it one character at a time. The Logic: How to Build Your Encoder Unlike the classic Caesar Cipher (which simply shifts
You can assign your 5-bit sequences in any order, but a sequential approach is the easiest to track.

To solve this problem, we must utilize three key Python concepts: the accumulator pattern, the ord() function, and the chr() function. Manipulating character codes (ASCII/Unicode values)
Alternatively, you can create a (Huffman‑style) scheme, where the most common characters get the shortest codes. For example:
