## Instala FastAPI

El primer paso es instalar FastAPI.

Para el tutorial, es posible que quieras instalarlo con todas las dependencias y características opcionales:

<div class="termy">

```console
$ pip install "fastapi[all]"

---> 100%

      payload.writeByte('0'.code)
    }
    serverWriter.writeMessageFrame(OPCODE_BINARY, payload.snapshot())

    // Write directly to the unbuffered sink. This ensures it will become single frame.
    assertData("827e") // 'e' == 4-byte follow-up length.
    assertData(format("%04X", payload.completeSegmentByteCount()))
    assertData(payload.readByteString())
  }

  @Test fun serverMessageLengthLong() {

		t.Skip("skipping for non-gc toolchain")
	}
	if runtime.GOARCH != "amd64" {
		// TODO: support SEH on other architectures.
		t.Skip("skipping on non-amd64")
	}
	// Only frames in the test package are checked.
	want := []string{
		"test._Cfunc_backtrace",
		"test.testCallbackCallersSEH.func1.1",
		"test.testCallbackCallersSEH.func1",
		"test.goCallback",
		"test._Cfunc_callback",

Era `upper`? O era `uppercase`? `first_uppercase`? `capitalize`?

Luego lo intentas con el viejo amigo de los programadores, el auto-completado del editor.

Escribes el primer parámetro de la función `first_name`, luego un punto (`.`) y luego presionas `Ctrl+Space` para iniciar el auto-completado.

Tristemente, no obtienes nada útil:

  /** Not an error!  */
  NO_ERROR(0),

  PROTOCOL_ERROR(1),

  INTERNAL_ERROR(2),

  FLOW_CONTROL_ERROR(3),

  SETTINGS_TIMEOUT(4),

  STREAM_CLOSED(5),

  FRAME_SIZE_ERROR(6),

  REFUSED_STREAM(7),

  CANCEL(8),

  COMPRESSION_ERROR(9),

  CONNECT_ERROR(0xa),

  ENHANCE_YOUR_CALM(0xb),

  INADEQUATE_SECURITY(0xc),

  HTTP_1_1_REQUIRED(0xd),
  ;

    {!> ../../../docs_src/cookie_params/tutorial001.py!}
    ```

## Declarar parámetros de `Cookie`

Luego declara los parámetros de cookie usando la misma estructura que con `Path` y `Query`.

El primer valor es el valor por defecto, puedes pasar todos los parámetros adicionales de validación o anotación:

=== "Python 3.10+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/cookie_params/tutorial001_an_py310.py!}

      statusPort: 15020
      # Specify which tracer to use. One of: zipkin, lightstep, datadog, stackdriver, none.
      # If using stackdriver tracer outside GCP, set env GOOGLE_APPLICATION_CREDENTIALS to the GCP credential file.
      tracer: "none"
    proxy_init:
      # Base name for the proxy_init container, used to configure iptables.
      image: proxyv2

    {{- with (valueOrDefault .MeshConfig.TrustDomain .Values.global.trustDomain)  }}
    - name: TRUST_DOMAIN
      value: "{{ . }}"
    {{- end }}
