## Use one HTTP operation per function

Don't mix HTTP operations in a single function, having one function per HTTP operation helps separate concerns and organize the code.

Do this:

```python
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

// maintains the map from `op_id` to a `OpTapeEntry` which stores the `op_type`,
// inputs and outputs and the gradient function These data structures combined
// allow us to trace the data dependencies between operations and hence compute
// gradients.
//
// `ZerosLike` is not expected to be called and returns a nullptr. The creation
// of default zeros grads is handled by the `DefaultGradientFunction` registered
// for each op.

 *
 * <ul>
 *   <li><b>Finite:</b> Many operations, such as {@link #length()} and {@link #read()}, will either
 *       block indefinitely or fail if the source creates an infinite reader.
 *   <li><b>Non-destructive:</b> A <i>destructive</i> reader will consume or otherwise alter the
 *       source as they are read from it. A source that provides such readers will not be reusable,

        failover.handleFailure(failedChannel, error);

        // Verify pending operations were cleared from failed channel
        assertEquals(0, failedChannel.getRequestsPending());

        // Verify alternative channel was selected and operation added
        verify(mockLoadBalancer).selectChannel(mockOperation);
        verify(alternativeChannel).addPendingOperation(mockOperation);

   * in a single load operation.
   */
  public double missRate() {
    long requestCount = requestCount();
    return (requestCount == 0) ? 0.0 : (double) missCount / requestCount;
  }

  /**
   * Returns the total number of times that {@link Cache} lookup methods attempted to load new
   * values. This includes both successful load operations and those that threw exceptions. This is

   * in a single load operation.
   */
  public double missRate() {
    long requestCount = requestCount();
    return (requestCount == 0) ? 0.0 : (double) missCount / requestCount;
  }

  /**
   * Returns the total number of times that {@link Cache} lookup methods attempted to load new
   * values. This includes both successful load operations and those that threw exceptions. This is

* une opération effectuée à distance par une API se termine
* une opération en base de données se termine
* une requête à une base de données renvoie un résultat
* etc.

Le temps d'exécution étant consommé majoritairement par l'attente d'opérations <abbr title="Input and Output - Entrées et sorties">I/O</abbr>, on appelle ceci des opérations « I/O bound ».

## Resumen { #recap }

Puedes añadir múltiples parámetros de cuerpo a tu *path operation function*, aunque un request solo puede tener un único cuerpo.

Pero **FastAPI** lo manejará, te dará los datos correctos en tu función, y validará y documentará el esquema correcto en la *path operation*.

También puedes declarar valores singulares para ser recibidos como parte del cuerpo.
