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]`

     */
    public static long readTime(final byte[] src, final int srcIndex) {
        final int low = readInt4(src, srcIndex);
        final int hi = readInt4(src, srcIndex + 4);
        long t = (long) hi << 32L | low & 0xFFFFFFFFL;
        return t / 10000L - SmbConstants.MILLISECONDS_BETWEEN_1970_AND_1601;
    }

    /**
     * Writes a Java time value as a Windows FILETIME

		for hi := len(s) - 1; hi >= 0; hi-- {
			c := s[hi]
			if c >= utf8.RuneSelf {
				return TrimFunc(s[:hi+1], unicode.IsSpace)
			}
			if asciiSpace[c] == 0 {
				// At this point, s[:hi+1] starts and ends with ASCII
				// non-space bytes, so we're done. Non-ASCII cases have
				// already been handled above.
				return s[:hi+1]
			}
		}
	}

        assertTrue(startsWithHello.apply("hello world"));
        assertTrue(startsWithHello.apply("hello"));
        assertFalse(startsWithHello.apply("hi world"));
        assertFalse(startsWithHello.apply(""));
        assertFalse(startsWithHello.apply(null));
    }

    @Test
    public void test_method_reference() {

예를 들어, 어떤 값이 `str` 또는 `None`이 될 수 있다고 선언할 수 있습니다:

```python
from typing import Union


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

`typing`에는 `None`이 될 수 있음을 선언하는 축약형으로 `Optional`도 있습니다.

아주 개인적인 관점에서의 팁입니다:

- 🚨 `Optional[SomeType]` 사용은 피하세요
- 대신 ✨ **`Union[SomeType, None]`를 사용하세요** ✨.

如果你的程式碼因某些原因無法使用 `|`，例如不是在型別註記中，而是在像 `response_model=` 之類的參數位置，那麼你可以用 `typing` 中的 `Union` 來取代豎線（`|`）。

例如，你可以宣告某個值可以是 `str` 或 `None`：

```python
from typing import Union


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

在 `typing` 中也有用 `Optional` 宣告某個值可以是 `None` 的速記法。

以下是我個人（非常主觀）的建議：

* 🚨 避免使用 `Optional[SomeType]`
* 改為 ✨ 使用 `Union[SomeType, None]` ✨。
