`__name__ == "__main__"` の主な目的は、ファイルが次のコマンドで呼び出されたときに実行されるコードを用意することです:

<div class="termy">

```console
$ python myapp.py
```

</div>

ただし、次のように、別のファイルからインポートされるときには呼び出されません:

```Python
from myapp import app
```

#### より詳しい説明

ファイルの名前が `myapp.py` だとします。

以下の様に実行する場合:

<div class="termy">

```console
$ python myapp.py
```

</div>

## 运行起来

之后，你只需要安装 `pytest`:

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

他会自动检测文件和测试，执行测试，然后向你报告结果。

执行测试：

<div class="termy">

```console
$ pytest

================ test session starts ================
platform linux -- Python 3.6.9, pytest-5.3.5, py-1.8.1, pluggy-0.13.1

## 安装 Gunicorn 和 Uvicorn

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

这将安装带有`standard`扩展包（以获得高性能）的 Uvicorn 和 Gunicorn。

## Run Gunicorn with Uvicorn Workers

接下来你可以通过以下命令运行Gunicorn:

<div class="termy">

```console
$ gunicorn main:app --workers 4 --worker-class uvicorn.workers.UvicornWorker --bind 0.0.0.0:80
