### `typing` module { #typing-module }

For some additional use cases, you might need to import some things from the standard library `typing` module, for example when you want to declare that something has "any type", you can use `Any` from `typing`:

```python
from typing import Any


def some_function(data: Any):
    print(data)
```

### Generic types { #generic-types }

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | Совет

`aGVsbG8=` — это base64-кодирование строки `hello`.

///

Затем Pydantic декодирует строку base64 и передаст вам исходные байты в поле `data` модели.

Вы получите такой HTTP-ответ:

```json
{
  "description": "Some data",
  "content": "hello"
}
```

			input: []byte(`id,time,num,num2,text
1,2010-01-01T,7867786,4565.908123
2,2017-01-02T03:04Z,-5, 0.765111,Some some
`),
			// Since we are doing offset, no headers are used.
			wantResult: `{"id":"1","time":"2010-01-01T","num":"7867786","num2":"4565.908123"}
{"id":"2","time":"2017-01-02T03:04Z","num":"-5","num2":" 0.765111","text":"Some some"}`,
			wantErr: false,
			requestXML: []byte(`<?xml version="1.0" encoding="UTF-8"?>

			// directory" error message. Handle this specifically
			// here.
			return errFileAccessDenied
		}
	}
	return err
}

// Reliably retries os.RemoveAll if for some reason os.RemoveAll returns
// syscall.ENOTEMPTY (children has files).
func reliableRemoveAll(dirPath string) (err error) {
	i := 0
	for {
		// Removes all the directories and files.

        )

        failureConditions {
            // JavaExecDebugIntegrationTest.debug session fails without debugger might cause JVM crash
            // Some soak tests produce OOM exceptions
            // There are also random worker crashes for some tests.
            // We have test-retry to handle the crash in tests
            javaCrash = false
        }
    })

Podrías enviar un request como:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | Consejo

`aGVsbG8=` es la codificación base64 de `hello`.

///

Y luego Pydantic decodificará el string base64 y te dará los bytes originales en el campo `data` del modelo.

  "description": "Some data",
  "content": "hello"
