Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

		}
	}

	deviceBin := fmt.Sprintf("%s/%s", deviceGotmp, binName)
	if err := adb("push", os.Args[1], deviceBin); err != nil {
		return 0, err
	}

	// Forward SIGQUIT from the go command to show backtraces from
	// the binary instead of from this wrapper.
	quit := make(chan os.Signal, 1)
	signal.Notify(quit, syscall.SIGQUIT)
	go func() {
		for range quit {
			// We don't have the PID of the running process; use the

/// note | Technical Details

You could also use `from starlette.responses import HTMLResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

///

### `Response` { #response }

The main `Response` class, all the other responses inherit from it.

You can return it directly.

  public void testIdentity() {
    for (CaseFormat from : CaseFormat.values()) {
      assertWithMessage("%s to %s", from, from).that(from.to(from, "foo")).isSameInstanceAs("foo");
      for (CaseFormat to : CaseFormat.values()) {
        assertWithMessage("%s to %s", from, to).that(from.to(to, "")).isEmpty();
        assertWithMessage("%s to %s", from, to).that(from.to(to, " ")).isEqualTo(" ");
      }
    }
  }

You can use:

* `HTTPException`
* `WebSocketException`

These exceptions can be imported directly from `fastapi`:

```python
from fastapi import HTTPException, WebSocketException
```

::: fastapi.HTTPException
