# Assignment 2 - Caesar Cipher
# Assignment 3 - Adam & Eve Subclasses
This is my code for the OOP homework. I chose the Caesar Cipher Helper.
This is my code for the Task 3 assignment using inheritance.

### How it works:
- The `CaesarCipher` class takes a `shift` number.
- `encode` changes text to uppercase and moves letters forward. It uses `% 26` so letters stay in the A-Z alphabet.
- `decode` moves letters backward to fix the text.
- Spaces and punctuation do not change.
### Tools:
I set up black and ruff with pre-commit hooks. They check and fix my code format before every commit.
- I created a base class called `Human`.
- `Man` and `Woman` are subclasses that inherit everything from `Human`.
- The `God` function creates and returns an array with the first man and woman.
