那么文件中由 Python 自动创建的内部变量 `__name__`，会将字符串 `"__main__"` 作为值。

所以，下面这部分代码才会运行：

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

---

如果你是导入这个模块（文件）就不会这样。

因此，如果你的另一个文件 `importer.py` 像这样：

```Python
from myapp import app

# Some more code
```

在这种情况下，`myapp.py` 内部的自动变量不会有值为 `"__main__"` 的变量 `__name__`。

所以，下面这一行不会被执行：

```Python

따라서 섹션

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

이 실행됩니다.

해당 모듈(파일)을 가져오면 이런 일이 발생하지 않습니다

그래서 다음과 같은 다른 파일 `importer.py`가 있는 경우:

```Python
from myapp import app

# Some more code
```

이 경우 `myapp.py` 내부의 자동 변수에는 값이 `"__main__"`인 변수 `__name__`이 없습니다.

따라서 다음 행

```Python

	src := "package x; import `unsafe`; var _ unsafe.Pointer;\n" + body

	var buf strings.Builder
	conf := types2.Config{
		Error:    func(err error) { fmt.Fprintln(&buf, err) },
		Importer: defaultImporter(),
	}
	typecheck(src, &conf, nil)
	if buf.Len() == 0 {
		return nil
	}
	return errors.New(strings.TrimRight(buf.String(), "\n"))
}

func TestMonoGood(t *testing.T) {
