# echo-app-py-uv
[](https://dibs.pages.dev/docs/build-systems/init/uv)
[](https://dibs.pages.dev/docs/build-systems/modular-design/uv)
This repository accompanies two lessons on building modern Python projects using [`uv`](https://docs.astral.sh/uv/), a fast and user-friendly tool for managing virtual environments and dependencies via `pyproject.toml`.
> 📘 The lessons are written in Spanish and can be found at:
>
> - [Lesson 1 – Basic setup](https://dibs.pages.dev/docs/build-systems/init/uv)
> - [Lesson 2 – Modular structure](https://dibs.pages.dev/docs/build-systems/modular-design/uv)
>
> However, the code and repository are written in English to ensure broader accessibility.
## 🧱 Project structure
This project follows a modular design using `uv workspaces`, separating business logic (`core`) from the application layer (`app`).
```
.
├── core
│ ├── echo_core
│ │ ├── __init__.py
│ │ └── echo.py
│ └── pyproject.toml
├── app
│ ├── echo_app
│ │ ├── __init__.py
│ │ └── main.py
│ └── pyproject.toml
├── pyproject.toml
├── uv.lock
└── README.md
```
## ▶️ How to run it
From the root directory, you can execute the application like this:
```bash
uv run app/echo_app/main.py Butcher Hughie Kimiko Frenchie M.M.
```
Expected output:
```text
Butcher
Hughie
Kimiko
Frenchie
M.M.
```
## 💡 What's inside?
The `core` module contains a reusable function:
```python
# core/echo_core/echo.py
def echo(message: str) -> str:
return message
```
The `app` module consumes it:
```python
# app/echo_app/main.py
from echo_core import echo
def main(args: list[str]):
for arg in args:
print(echo(arg))
if __name__ == "__main__":
import sys
main(sys.argv[1:])
```
## 📖 Learn more
These lessons guide you from a simple script to a **modular and scalable project structure**, preparing you for more advanced topics like testing, packaging, and CI.
