```Python
async with lifespan(app):
    await do_stuff()
```

When you create a context manager or an async context manager like above, what it does is that, before entering the `with` block, it will execute the code before the `yield`, and after exiting the `with` block, it will execute the code after the `yield`.

### Crie uma classe `Enum` { #create-an-enum-class }

Importe `Enum` e crie uma subclasse que herde de `str` e de `Enum`.

Ao herdar de `str`, a documentação da API saberá que os valores devem ser do tipo `string` e poderá renderizá-los corretamente.

Em seguida, crie atributos de classe com valores fixos, que serão os valores válidos disponíveis:

{* ../../docs_src/path_params/tutorial005_py39.py hl[1,6:9] *}

/// tip | Dica

Importieren Sie `Enum` und erstellen Sie eine Unterklasse, die von `str` und `Enum` erbt.

Indem Sie von `str` erben, weiß die API-Dokumentation, dass die Werte vom Typ `str` sein müssen, und wird in der Lage sein, korrekt zu rendern.

Erstellen Sie dann Klassen-Attribute mit festgelegten Werten, welches die erlaubten Werte sein werden:

{* ../../docs_src/path_params/tutorial005_py39.py hl[1,6:9] *}


/// tip | Tipp

Then create class attributes with fixed values, which will be the available valid values:

{* ../../docs_src/path_params/tutorial005_py39.py hl[1,6:9] *}

/// tip

If you are wondering, "AlexNet", "ResNet", and "LeNet" are just names of Machine Learning <abbr title="Technically, Deep Learning model architectures">models</abbr>.

### Declare a *path parameter* { #declare-a-path-parameter }

hanging from the roof.

  There were doors all round the hall, but they were all locked;
and when Alice had been all the way down one side and up the
other, trying every door, she walked sadly down the middle,
wondering how she was ever to get out again.

  Suddenly she came upon a little three-legged table, all made of
solid glass; there was nothing on it except a tiny golden key,

console on their browser, and selects the OpenID Provider they wish to use (the `MINIO_IDENTITY_OPENID_DISPLAY_NAME` value is shown here). The user is then redirected to the OpenID provider's login page and performs necessary login actions (e.g. entering credentials, responding to MFA authentication challenges, etc). After successful login, the user is redirected back to the MinIO console. This redirect URL is specified as a parameter by MinIO when the user is redirected to the OpenID Provider in...

We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

And there has to be something in charge of **renewing the HTTPS certificates**, it could be the same component or it could be something different.

### Example Tools for HTTPS { #example-tools-for-https }

Some of the tools you could use as a TLS Termination Proxy are:

				p.errorf("unexpected EOF")
				return "", "", nil, false
			}
			// Split operands on comma. Also, the old syntax on x86 for a "register pair"
			// was AX:DX, for which the new syntax is DX, AX. Note the reordering.
			if tok == '\n' || tok == ';' || (nesting == 0 && (tok == ',' || tok == ':')) {
				if tok == ':' {
					// Remember this location so we can swap the operands below.
					if colon >= 0 {

							ver.header = version.header()
							ver.meta = meta
						}
					}
				}
			}
		}

		// Fix inconsistent x-minio-internal-replication-timestamp by loading and reindexing.
		if metaV < 2 && ver.header.Type == DeleteType {
			// load (and convert) version.
			version, err := x.getIdx(i)
			if err == nil {
				// Only reindex if set.

  - Some kubeadm commands are now allowed to work in a completely offline mode.
- Certificate handling improvements:
  - Renew certs as part of upgrade.
  - New `kubeadm alpha phase certs renew` command for renewing certificates.
  - Certificates created with kubeadm now have improved uniqueness of Distinguished Name fields.
- HA improvements:
