یعنی **هر مقداری** که توی پایتون از یه متغیر محیطی خونده می‌شه یه `str` هست، و هر تبدیل به نوع دیگه یا هر اعتبارسنجی باید توی کد انجام بشه.

توی [راهنمای کاربر پیشرفته - تنظیمات و متغیرهای محیطی](./advanced/settings.md){.internal-link target=_blank} بیشتر در مورد استفاده از متغیرهای محیطی برای مدیریت **تنظیمات برنامه** یاد می‌گیری.

## متغیر محیطی `PATH`

COPY ./app /app
```

### Applications plus larges

Si vous avez suivi la section sur la création d' [Applications avec plusieurs fichiers](../tutorial/bigger-applications.md){.internal-link target=_blank}, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app/app
```

### Raspberry Pi et autres architectures

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package cmd

import (
	"net/http"
	"net/url"
	"strings"
	"time"

	"github.com/minio/minio/internal/auth"
	xhttp "github.com/minio/minio/internal/http"
)

// credentialHeader data type represents structured form of Credential
// string from authorization header.
type credentialHeader struct {
	accessKey string
	scope     struct {

# NOTE: This Dockerfile is no longer in use.
# It is kept just in case, but it's recommended to use the 2022 version,
# and that is what internal CI uses as well.

# This Dockerfile creates an image that has:
# - the correct MTU setting for networking from inside the container to work.
# - Visual Studio 2022 Build Tools
# - MSVC 14.39
# - LLVM/Clang 18.1.4
# - MSYS2 + curl, git, patch, vim, unzip, zip
# - Python 3.12.3
# - Bazelisk 1.19.0

`TestClient` 是基于 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> 的。幸运的是，我们可以直接使用它来测试API。

## 示例

举个简单的例子，让我们来看一个[更大的应用](../tutorial/bigger-applications.md){.internal-link target=_blank}和[测试](../tutorial/testing.md){.internal-link target=_blank}中描述的类似文件结构：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

文件 `main.py` 将包含:

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