Hi, your job is to interpret a function f(x) that is implemented in the ./temp/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp/function.py string). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp/function.py string1 string2 string3 ...). 
We encourage testing a large range of inputs before writing a description.
The goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
Your description of the function should be in the following form.
[DESCRIPTION]: Describe what the function is doing in language. 
[CODE]: Write python code that approximates the behavior of the function. 
assistant:
Alright, let's start with some initial test inputs to understand the function's behavior.

COMMAND: PYTHON(./temp/function.py "test" "hello" "world" "python")
user:
Response: Function input - output pairs: (test, testKx) (hello, helloKx) (world, worldKx) (python, pythonKx) 

assistant:
Interesting, it seems that the function is appending "Kx" to the input string. Let's try some additional test inputs with different characters and lengths.

COMMAND: PYTHON(./temp/function.py "abc" "123" "!@#" "longerstring" "")
user:
Response: Function input - output pairs: (abc, abcKx) (123, 123Kx) (!@#, !@#Kx) (longerstring, longerstringKx) (, Kx) 

assistant:
[DESCRIPTION]: The function appends the string "Kx" to the input string.

[CODE]:
```python
def f(x):
    return x + "Kx"
```
