But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎

///

The dependencies will keep working as expected, and the **best part** is that the **type information will be preserved**, which means that your editor will be able to keep providing you with **autocompletion**, **inline errors**, etc. The same for other tools like `mypy`.

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

### `Body` with `examples` { #body-with-examples }

Here we pass `examples` containing one example of the data expected in `Body()`:

{* ../../docs_src/schema_extra_example/tutorial003_an_py310.py hl[22:29] *}

### Example in the docs UI { #example-in-the-docs-ui }

With any of the methods above it would look like this in the `/docs`:

            SMBProtocolDecodingException exception =
                    assertThrows(SMBProtocolDecodingException.class, () -> notification.readBytesWireFormat(buffer, 0));

            assertEquals("Expected structureSize = 24", exception.getMessage());
        }

        @ParameterizedTest
        @DisplayName("Should read different oplock levels correctly")

	}

again:
	nextOut, ok := w.buffer[w.nextOffset]
	if ok {
		n, err = w.w.Write(nextOut)
		delete(w.buffer, w.nextOffset)
		w.nextOffset += int64(n)
		if n != len(nextOut) {
			return 0, fmt.Errorf("expected write size %d but wrote %d bytes", len(nextOut), n)
		}
		if err != nil {
			return 0, err
		}
		goto again
	}

	return len(b), nil
}
