# \*\*kwargs 的用法

`**kwargs` 允许你将不定长度的**键值对**，作为参数传递给一个函数。如果你想要在一个函数里处理**带名字的参数**，你应该使用`**kwargs`。

这里有个让你上手的例子:

```python
def greet_me(**kwargs):
    for key, value in kwargs.items():
        print("{0} == {1}".format(key, value))


>>> greet_me(name="yasoob")
name == yasoob
```

现在你可以看出我们怎样在一个函数里，处理了一个**键值对**参数了。

这就是 `**kwargs` 的基础，而且你可以看出它有多么管用。接下来让我们谈谈，你怎样使用 `*args` 和 `**kwargs` 来调用一个参数为列表或者字典的函数。
