Nokta (`.`) ile başlayan dosyalar, Linux ve macOS gibi Unix-benzeri sistemlerde gizli dosyadır.

Ancak dotenv dosyasının mutlaka bu dosya adına sahip olması gerekmez.

Bu küçük örneğin `await` ifadesine ihtiyacı olmadığı için, event loop’un iptali ele alabilmesi adına `await anyio.sleep(0)` ekliyoruz.

Büyük veya sonsuz akışlarda bu daha da önemlidir.

# Virtual Environments { #virtual-environments }

Python projeleriyle çalışırken, her proje için kurduğunuz package'leri birbirinden izole etmek adına büyük ihtimalle bir **virtual environment** (veya benzer bir mekanizma) kullanmalısınız.

/// info | Bilgi

Virtual environment'leri, nasıl oluşturulduklarını ve nasıl kullanıldıklarını zaten biliyorsanız bu bölümü atlamak isteyebilirsiniz. 🤓

The `security_scopes` object (of class `SecurityScopes`) also provides a `scope_str` attribute with a single string, containing those scopes separated by spaces (we are going to use it).

We create an `HTTPException` that we can reuse (`raise`) later at several points.

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

So, in OpenAPI, each of the HTTP methods is called an "operation".

We are going to call them "**operations**" too.

#### Define a *path operation decorator* { #define-a-path-operation-decorator }

	SkipRebalancing bool

	SrcPoolIdx int // set by PutObject/CompleteMultipart operations due to rebalance; used to prevent rebalance src, dst pools to be the same

	DataMovement bool // indicates an going decommisionning or rebalacing

	PrefixEnabledFn func(prefix string) bool // function which returns true if versioning is enabled on prefix

	// IndexCB will return any index created but the compression.
