您可以在 shell 中创建和使用环境变量，而无需使用 Python：

//// tab | Linux、macOS、Windows Bash

<div class="termy">

```console
// 您可以创建一个名为 MY_NAME 的环境变量
$ export MY_NAME="Wade Wilson"

// 然后您可以与其他程序一起使用它，例如
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
// 创建一个名为 MY_NAME 的环境变量
$ $Env:MY_NAME = "Wade Wilson"

			keys:     []string{"etag", "md5"},
			want:     map[string]string{"content-type": "application/octet-stream", "x-amz-storage-class": "STANDARD"},
		},
		{
			name:     "2",
			metadata: map[string]string{"content-type": "application/octet-stream", "etag": "de75a98baf2c6aef435b57dd0fc33c86", "x-amz-storage-class": "REDUCED_REDUNDANCY", "md5sum": "abcde"},

## Kurulum

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

<div class="termy">

</div>

mais qui n'est pas appelé lorsqu'un autre fichier l'importe, comme dans :

```Python
from myapp import app
```

#### Pour davantage de détails

Imaginons que votre fichier s'appelle `myapp.py`.

Si vous l'exécutez avec :

<div class="termy">

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

<div class="termy">

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

</div>

mas não é chamado quando outro arquivo o importa, como em:

```Python
from myapp import app
```

#### Mais detalhes { #more-details }

Digamos que seu arquivo se chama `myapp.py`.

Se você executá-lo com:

<div class="termy">

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