<summary>または<code>async def</code>を使います...</summary>

`async` / `await`を使用するときは、 `async def`を使います:

```Python hl_lines="7 12"
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}

            });
        }

        // Start all threads
        for (Thread thread : threads) {
            thread.start();
        }

        // Wait for all threads to complete
        for (Thread thread : threads) {
            thread.join();
        }

        // All results should be the same
        String expectedValue = "Test Fess";

                // Remove the waiter, one way or another we are done parking this thread.
                removeWaiter(node);
                break long_wait_loop; // jump down to the busy wait loop
              }
            }
          }
          oldHead = waitersField; // re-read and loop.
        } while (oldHead != Waiter.TOMBSTONE);
      }

No importa. **FastAPI** sabrá qué hacer.

## Integración con OpenAPI

Todas las declaraciones de request, validaciones y requisitos de tus dependencias (y sub-dependencias) se integrarán en el mismo esquema de OpenAPI.

        for (WitnessRegistration registration : registrations.values()) {
            unregisterFutures.add(unregister(registration));
        }

        // Wait for all unregistrations to complete
        try {
            CompletableFuture.allOf(unregisterFutures.toArray(new CompletableFuture[0])).get(10, TimeUnit.SECONDS);
        } catch (Exception e) {

**reflected** on the client code automatically. And if you **build** the client, it will error out if you have any **mismatch** in the data used.

So, you would **detect many errors** very early in the development cycle instead of having to wait for the errors to show up to your final users in production and then trying to debug where the problem is. ✨...

<summary>Ya da <code>async def</code>...</summary>

Eğer kodunuzda `async` / `await` varsa, `async def` kullanalım:

```Python hl_lines="9  14"

                    // In a real implementation, we would:
                    // 1. Send SMB2 Change Notify request
                    // 2. Wait for response
                    // 3. Process changes
                    // 4. Notify the lease manager

                    // Use adaptive polling interval based on activity
