* There's also an `app/dependencies.py` file, just like `app/main.py`, it is a "module": `app.dependencies`.
* There's a subdirectory `app/routers/` with another file `__init__.py`, so it's a "Python subpackage": `app.routers`.
* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.

    ```

* `app` 目录包含了所有内容。并且它有一个空文件 `app/__init__.py`，因此它是一个「Python 包」（「Python 模块」的集合）：`app`。
* 它包含一个 `app/main.py` 文件。由于它位于一个 Python 包（一个包含 `__init__.py` 文件的目录）中，因此它是该包的一个「模块」：`app.main`。
* 还有一个 `app/dependencies.py` 文件，就像 `app/main.py` 一样，它是一个「模块」：`app.dependencies`。
* 有一个子目录 `app/routers/` 包含另一个 `__init__.py` 文件，因此它是一个「Python 子包」：`app.routers`。
* 文件 `app/routers/items.py` 位于 `app/routers/` 包中，因此它是一个子模块：`app.routers.items`。

### Crie o código **FastAPI**

* Crie um diretório `app` e entre nele.
* Crie um arquivo `main.py` com:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}
