我猜问题的原因是KNN.py修改后，python没有来得及加载为什么要用array, array 很麻烦的说 不是你这样用的array('l')array('u', 'hello \u2641')array('l', [1, 2, 3, 4, 5])array('d', [1.0, 2.0, 3.14])外面再套一个list不行么
When working with a function that has both default and non-default arguments, consider using keyword arguments in the function call to make the code more readable and less error-prone. By following these best practices, you'll be able to write more robust and maintainable Python code ...

In a function, the order in which arguments must appear is: Positional arguments (non-default) Keyword arguments (default) Keyword-only arguments (*args) Variable keyword arguments (**kwargs) If you do not adhere to this order, Python returns an error message. An Example Scenario Write a pr...

The HTTP url pattern is http://localhost:4104/*namespace*/*function-name*.*format*. Arguments are encoded in format, and posted to server via HTTP body. If you have multiple arguments, you should put them into a clojure vector (for clj format) or javascript array (for json format)....
