Key Concepts & Vocabulary
TermDefinitionExample
Directory StructureThe way files and folders are organized within a project. A good structure makes the project easy to navigate and understand.A project folder named `my_game/` containing sub-folders like `src/` for code, `assets/` for images, and a `README.md` file.
ModuleA separate file containing code (like functions or classes) that can be imported and used in other parts of the project.A `player.py` file that contains the `Player` class for a game, which is then imported into the main `game.py` file using `from player import Player`.
Source Code (`src`)The folder where all the primary programming files (e.g., `.py`, `.js`, `.java`) are stored.In a project, all your Python files like `main.py` and `utils.py` would live inside the `my_project/src/` directory.

Core Syntax & Patterns
Separation of Concerns
Group files by their purpose or function.
Keep your logic (source code), data (assets), and documentation in separate, clearly named folders. This makes it easy to find what you're looking for and understand the role of each part of the project.
The Root Directory Rule
The main project folder (root) should be clean and contain only essential files and top-level directories.
Avoid cluttering the root directory with dozens of individual files. It should typically contain your `src` folder, `assets` folder, `README.md`, and maybe a configuration file.
Modular Import Syntax
from <filename> import <function_or_class>
This is the common programming pattern used to access code from one file (a module) inside another. It's the mec...

You are tasked with reorganizing a simple website project that currently has all files (`index.html`, `style.css`, `app.js`, `logo.png`, `background.jpg`) in a single folder. Which of the following represents the BEST new directory structure based on the tutorial's principles?
A.root/
- index.html
- style.css
- app.js
- logo.png
- background.jpg
B.root/
- src/
- index.html

- logo.png
- background.jpg
C.root/
- index.html
- css/
- style.css
- js/
- app.js
- images/
- logo.png
- background.jpg
D.root/
- code/
- index.html
- style.css

A game developer has hardcoded the game window's width and height in 20 different files. When they decide to change the resolution, they have to find and replace the values in all 20 locations, and they miss one, causing a bug. How would creating a `config.json` file with `{"width": 800, "height": 600}` and having the code read from it have prevented this specific problem?
A.It would make the code run faster by pre-loading the settings.
B.It would provide a single, authoritative source for the settings, so the change only needs to be made in one place.
C.It would automatically convert the game to the new resolution without any code changes.
D.It would add comments to the code reminding the developer where to change the values.

You are starting a new Python project for a school science fair that will simulate planetary orbits. The project will involve complex physics calculations, displaying the simulation visually, and reading planet data from a CSV file. Based on the tutorial, which initial directory structure plan is the most robust and organized?

B.root/
- main.py
- physics.py
- visuals.py
- planet_data.csv
- README.md
C.root/
- src/
- main.py
- physics_engine.py
- visual_display.py
- assets/
- data/
- planet_data.csv
- README.md
D.root/
- code_and_data/
- main.py
- physics_engine.py
- visual_display.py
- planet_data.csv
- README.md
