因此，下面的函数会针对每个参数组合执行一次。然后，当以完全相同的参数组合调用该函数时，将重复使用该参数组合先前返回的值。

例如，如果你有一个函数：

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

你的程序可能会像这样执行：

```mermaid

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