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 me start by testing some inputs to the f(x) function.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "123" "example")
user:
Response: Function input - output pairs: (hello, nkrrx) (world, cuxrm) (test, zkyc) (123, 123) (example, kdgsvrn) 

assistant:
Thank you for the response. Let me try with more inputs.

COMMAND: PYTHON(./temp/function.py "python" "apple" "banana" "Orange" "Coding" "WXYZ" "abcd")
user:
Response: Function input - output pairs: (python, veznuw) (apple, gvvrn) (banana, hgtgtj) (Orange, Uxgtmn) (Coding, Iujotp) (WXYZ, CDEG) (abcd, ghim) 

assistant:
Based on the given input-output pairs, it seems that the function is doing some character transformation. Let me try a different set of inputs to confirm the pattern.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "Z" "a" "b" "c" "z")
user:
Response: Function input - output pairs: (A, J) (B, K) (C, L) (Z, G) (a, j) (b, k) (c, l) (z, g) 

assistant:
Based on the given input-output pairs, it appears that the function is applying a Caesar cipher with a shift of 9 in the alphabet for each character (case-sensitive). Let me provide you with the description and code.

[DESCRIPTION]: The function applies a Caesar cipher with a shift of 9 to the input string, keeping the case of the characters intact.

[CODE]:
```python
def approx_function(s):
    result = []
    for char in s:
        if 'a' <= char <= 'z':
            shifted = chr(((ord(char) - ord('a') + 9) % 26) + ord('a'))
        elif 'A' <= char <= 'Z':
            shifted = chr(((ord(char) - ord('A') + 9) % 26) + ord('A'))
        else:
            shifted = char
        result.append(shifted)
    return ''.join(result)
```
