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:

## 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%

    assertThat(firstFrame(logs, "HEADERS")!!, "header logged")
      .contains("HEADERS       END_HEADERS")
    // While MockWebServer waits to read the client's HEADERS frame before sending the response, it
    // doesn't wait to read the client's DATA frame and may send a DATA frame before the client
    // does. So we can't assume the client's empty DATA will be logged first.

      .isEqualTo("<< 0x00000003   226 DATA          END_STREAM")
    assertThat(frameLog(false, 0, 8, TYPE_GOAWAY, FLAG_NONE))
      .isEqualTo(">> 0x00000000     8 GOAWAY        ")
  }

  /** Window update frames have special formatting.  */
  @Test
  fun windowUpdateFrames() {
    assertThat(frameLogWindowUpdate(false, 0, 4, Int.MAX_VALUE.toLong()))
      .isEqualTo(">> 0x00000000     4 WINDOW_UPDATE 2147483647")
