```Python
class Cat:
    def __init__(self, name: str):
        self.name = name

```console
// Here we don't set the env var yet
$ python main.py

// As we didn't set the env var, we get the default value

Hello World from Python

// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"

// And then call the program again
$ python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python
```

Para receber arquivos enviados, primeiro instale o <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e então o instalou, por exemplo:

```console
$ pip install python-multipart
```

以下の様に実行する場合:

<div class="termy">

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

</div>

Pythonによって自動的に作成されたファイル内の内部変数 `__name__` は、値として文字列 `"__main__"` を持ちます。

なので、以下:

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

は実行されます。

そのモジュール (ファイル) をインポートした場合は、こうはなりません。

したがって、次のようなもう一つのファイル `importer.py` がある場合:

```Python
from myapp import app

# Some more code
