### About `__name__ == "__main__"`

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<div class="termy">

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

</div>

but is not called when another file imports it, like in:

```Python
from myapp import app
```

#### More details

Let's say your file is named `myapp.py`.

For example, you could create a project called `philosophers-stone`, this program depends on another package called **`harry`, using the version `1`**. So, you need to install `harry`.

```mermaid
flowchart LR
    stone(philosophers-stone) -->|requires| harry-1[harry v1]
```

     首先仅复制requirements.txt文件，而不复制其余代码。

     由于此文件**不经常更改**，Docker 将检测到它并在这一步中使用**缓存**，从而为下一步启用缓存。

4. 安装需求文件中的包依赖项。

     `--no-cache-dir` 选项告诉 `pip` 不要在本地保存下载的包，因为只有当 `pip` 再次运行以安装相同的包时才会这样，但在与容器一起工作时情况并非如此。

     /// note | 笔记

     `--no-cache-dir` 仅与 `pip` 相关，与 Docker 或容器无关。

     ///

     `--upgrade` 选项告诉 `pip` 升级软件包（如果已经安装）。
