`@lru_cache` 會修改它所裝飾的函式，使其回傳第一次回傳的相同值，而不是每次都重新計算、執行函式碼。

因此，被裝飾的函式對於每組參數組合只會執行一次。之後，凡是以完全相同參數組合呼叫時，都會重複使用先前對應的回傳值。

例如，如果你有一個函式：

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

你的程式可能會這樣執行：

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

For example, if you have a function:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

your program could execute like this:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function
