**FastAPI** целиком основан на аннотациях типов, у них много выгод и преимуществ.

Но даже если вы никогда не используете **FastAPI**, вам будет полезно немного узнать о них.

/// note

Если вы являетесь экспертом в Python и уже знаете всё об аннотациях типов, переходите к следующему разделу.

## Мотивация

Давайте начнем с простого примера:

```Python

infrastructure that runs MinIO is configured correctly, and is functioning properly. This test is one-shot long running one, that is recommended to be run as soon as the cluster is first provisioned, and each time a failure scenario is encountered. Note that the test incurs majority of the available resources on the system. Care must be taken when using this to debug failure scenario, so as to prevent larger outages. Health tests can be triggered using `mc support diagnostics` command.

Example:...

		Help:      "Total number of bytes sent to the other peer nodes",
		Type:      counterMetric,
	}
}

func getInterNodeReceivedBytesMD() MetricDescription {
	return MetricDescription{
		Namespace: interNodeMetricNamespace,
		Subsystem: trafficSubsystem,
		Name:      receivedBytes,
		Help:      "Total number of bytes received from other peer nodes",
		Type:      counterMetric,
	}
}

```

Then, declare your *path operation functions* with `async def` like:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note

You can only use `await` inside of functions created with `async def`.

	if hdr.Typeflag == TypeGNUSparse {
		spd, err = tr.readOldGNUSparseMap(hdr, rawHdr)
	} else {
		spd, err = tr.readGNUSparsePAXHeaders(hdr)
	}

	// If sp is non-nil, then this is a sparse file.
	// Note that it is possible for len(sp) == 0.
	if err == nil && spd != nil {
		if isHeaderOnlyType(hdr.Typeflag) || !validateSparseEntries(spd, hdr.Size) {
			return ErrHeader
		}
		sph := invertSparseEntries(spd, hdr.Size)

  }

  // Test suppression

**FastAPI** kullanmayacak olsanız bile tür belirteçleri hakkında bilgi edinmenizde fayda var.

## Motivasyon

Basit bir örnek ile başlayalım:

```Python

    }

    void clear() {
      value = null;
    }
  }

  private static final class AvlNode<E extends @Nullable Object> {
    /*
     * For "normal" nodes, the type of this field is `E`, not `@Nullable E` (though note that E is a
     * type that can include null, as in a TreeMultiset<@Nullable String>).
     *
     * For the header node, though, this field contains `null`, regardless of the type of the
