接着，对于后续请求中依赖项里对 `get_settings()` 的任何调用，它不会再次执行 `get_settings()` 的内部代码并创建新的 `Settings` 对象，而是会一遍又一遍地返回第一次调用时返回的那个相同对象。

#### `lru_cache` 技术细节 { #lru-cache-technical-details }

`@lru_cache` 会修改它所装饰的函数，使其返回第一次返回的相同值，而不是每次都重新计算并执行函数代码。

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
