* Создайте файл `main.py` со следующим содержимым:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile { #dockerfile }

Depois de ativar o ambiente virtual, você pode executar seu programa, e ele usará o Python dentro do seu ambiente virtual com os pacotes que você instalou lá.

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## Configure seu editor { #configure-your-editor }

Después de activar el entorno virtual, puedes ejecutar tu programa, y usará el Python dentro de tu entorno virtual con los paquetes que instalaste allí.

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## Configura Tu Editor { #configure-your-editor }

response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.

response = requests.get("http://example.com/some/url")
```

La operación de path equivalente en FastAPI podría verse como:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

A contra-parte na aplicação FastAPI, a operação de rota, poderia ficar assim:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

```Python hl_lines="1"

## 執行程式

在啟用虛擬環境後，你可以執行你的程式，它將使用虛擬環境中的 Python 和你在其中安裝的套件。

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## 設定編輯器

你可能會用到編輯器，請確保設定它使用你建立的相同虛擬環境（它可能會自動偵測到），以便你可以獲得自動完成和内嵌錯誤提示。

例如：
