Наприклад, ви можете оголосити, що щось може бути `str` або `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

У `typing` також є скорочення, щоб оголосити, що щось може бути `None`, - `Optional`.

Ось порада з моєї дуже «суб'єктивної» точки зору:

- 🚨 Уникайте використання `Optional[SomeType]`

	for algorithm := range bitrotAlgorithms {
		if !algorithm.Available() {
			continue
		}

		checksum, err := hex.DecodeString(checksums[algorithm])
		if err != nil {
			logger.Fatal(errSelfTestFailure, fmt.Sprintf("bitrot: failed to decode %v checksum %s for selftest: %v", algorithm, checksums[algorithm], err))
		}
		var (
			hash = algorithm.New()
			msg  = make([]byte, 0, hash.Size()*hash.BlockSize())

					errStr = fmt.Sprintf("no results for downloads upon first attempt, concurrency %d and duration %s",
						opts.concurrencyStart, opts.duration)
				}

				// if the default concurrency yields zero results, throw an error.
				if throughputHighestResults[i].Uploads == 0 && opts.concurrencyStart == concurrency {

Por ejemplo, podrías declarar que algo podría ser un `str` o `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` también tiene un atajo para declarar que algo podría ser `None`, con `Optional`.

Aquí va un Consejo desde mi punto de vista muy subjetivo:

* 🚨 Evita usar `Optional[SomeType]`

For example, you could declare that something could be a `str` or `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` also has a shortcut to declare that something could be `None`, with `Optional`.

Here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
