O arquivo `main.py` teria:

{* ../../docs_src/async_tests/app_a_py39/main.py *}

O arquivo `test_main.py` teria os testes para para o arquivo `main.py`, ele poderia ficar assim:

{* ../../docs_src/async_tests/app_a_py39/test_main.py *}

## Executá-lo { #run-it }

Você pode executar os seus testes normalmente via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

環境変数をPythonの**外側**、ターミナル（や他の方法）で作成し、**Python内で読み取る**こともできます。

例えば、以下のような`main.py`ファイルを用意します:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> の第2引数は、デフォルトで返される値を指定します。

この引数を省略するとデフォルト値として`None`が返されますが、ここではデフォルト値として`"World"`を指定しています。
