+Similarly, Python can expand a dictionary using `**`.
+
+```
+def some_fn(a, b, c):
+    print(a, b, c) # 1 2 3
+
+my_dict = {"c": 3, "b": 2, "a": 1} # Python has no requirement for the order of keys in a dictionary
+some_fn(**my_dict)
+
+```

 While `*args` and `**kwargs` are convenient, if a function only has these parameters, IDE code suggestions will be lost, and the logic of the function may become harder to understand. Therefore, use them with caution.

+类似地，Python 也可以使用 `**` 展开一个字典

 `*args` 和 `**kwargs` 虽然方便，但如果函数只定义了这两个形参，IDE 将失去代码提示，同时函数的逻辑也将变得难以理解，需要谨慎使用。
