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

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Camila")
        function ->> execute: execute function code

        //
        // The projects need to be topologically after the participants have run their afterProjectsRead(session)
        // because the participant is free to change the dependencies of a project which can potentially change the
        // topological order of the projects, and therefore can potentially change the build order.
        //
        // Note that participants may affect the topological order of the projects but it is

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

您的程序可以像这样执行：

```mermaid
sequenceDiagram

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

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Camila")
        function ->> execute: 执行函数代码
        execute ->> code: 返回结果

        resolutionAction.execute(result);
        if (selected != null) {
            maybeSetReason(conflict.participants, selected);
        }
        LOGGER.debug("Selected {} from conflicting modules {}.", selected, conflict.candidates);
    }

    private void maybeSetReason(Set<ModuleIdentifier> partifipants, ComponentResolutionState selected) {
