   * Returns the stack trace of {@code throwable}, possibly providing slower iteration over the full
   * trace but faster iteration over parts of the trace. Here, "slower" and "faster" are defined in

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Por baixo dos panos, o código `open("./somefile.txt")` cria um objeto que é chamado de "Gerenciador de Contexto".

Quando o bloco `with` finaliza, ele se certifica de fechar o arquivo, mesmo que tenha ocorrido alguma exceção.

Those details are implementation specific.

For OAuth2 they are just strings.

First, let's quickly see the parts that change from the examples in the main **Tutorial - User Guide** for [OAuth2 with Password (and hashing), Bearer with JWT tokens](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Now using OAuth2 scopes:

	ObjectAttributes    map[string]struct{} // Attribute tags defined by the users for the GetObjectAttributes request
	MaxParts            int                 // used in GetObjectAttributes. Signals how many parts we should return
	PartNumberMarker    int                 // used in GetObjectAttributes. Signals the part number after which results should be returned

		DiskID:   *client.diskID.Load(),
		Volume:   volume,
		FilePath: path,
		Buf:      b,
	})
	return toStorageErr(err)
}

// CheckParts - stat all file parts.
func (client *storageRESTClient) CheckParts(ctx context.Context, volume string, path string, fi FileInfo) (*CheckPartsResp, error) {
	var resp *CheckPartsResp

 * }
 * ```
 *
 * which prints:
 *
 * ```
 * q: cute #puppies
 * f: images
 * ```

 * In addition to composing URLs from their component parts and decomposing URLs into their
 * component parts, this class implements relative URL resolution: what address you'd reach by
 * clicking a relative link on a specified page. For example:
