</div>

then the internal variable `__name__` in your file, created automatically by Python, will have as value the string `"__main__"`.

So, the section:

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

will run.

---

This won't happen if you import that module (file).

So, if you have another file `importer.py` with:

```Python
from myapp import app

# Some more code
```

Shinsuke Sugaya <******@****.***> 1576358545 +0900

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

    # Update the viewport manually
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_label("post /heroes/").click()

    page.screenshot(path="docs/en/docs/img/tutorial/sql-databases/image01.png")

    # ---------------------
    context.close()

$ python myapp.py
```

</div>

тоді внутрішня змінна `__name__`, яка створюється автоматично Python, матиме значення `"__main__"`.

Отже, цей блок коду:

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

буде виконаний.

Це не станеться, якщо Ви імпортуєте цей модуль (файл).

Якщо у Вас є інший файл, наприклад `importer.py`, з наступним кодом:

```Python
from myapp import app

    context = browser.new_context(viewport={"width": 960, "height": 1080})
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context()
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="GET /items/ Read Items").click()
    page.get_by_role("button", name="Try it out").click()
    page.get_by_role("heading", name="Servers").click()
    # Manually add the screenshot
