8.3 8 Create Your Own Encoding - Codehs Answers

A computer doesn't know what "A" looks like; it only knows 01000001 (in ASCII).

A) ListB) TupleC) DictionaryD) Set Correct Answer: C) Dictionary ✅

: The for char in secret_text: loop evaluates the message character by character. For example, if the user inputs "Hi", the loop runs twice: 8.3 8 create your own encoding codehs answers

: Translates a character into its ASCII integer value.

The autograder usually supplies a secret test string like "hello world" or "CodeHS 8.3.8" . Your encoding must survive round-trip conversion. A computer doesn't know what "A" looks like;

Other variations require you to reverse the string and then shift characters. However, the most common version of asks for a dictionary-based substitution cipher .

The assignment often encourages you to . You could: The autograder usually supplies a secret test string

Master CodeHS 8.3.8: Create Your Own Encoding Encoding algorithms form the backbone of modern data security and computer science. In the CodeHS "Create Your Own Encoding" exercise, you move beyond basic substitution ciphers to build a custom text encryption system using Python.

Here is a Python implementation of a custom encoding algorithm that satisfies the assignment requirements.

Test original: CodeHS 8.3.8 is fun! Test encoded: C O U4 U5 U8 U19 _ 8 . 3 . 8 _ U9 U19 _ U6 U21 U14 ! Test decoded: CodeHS 8.3.8 is fun!

Dictionaries are designed for key-value pairs , allowing you to look up a letter (the key) and instantly retrieve its encoded symbol (the value). Lists or Tuples would require you to loop through every item just to find one match, which is much slower. If you'd like, I can help you: Debug a specific error message you're getting. Show you how to write the decoding function (the reverse).
