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.

Alright, let's start by testing the function with some basic string inputs.

COMMAND: PYTHON(./temp/function.py "abc" "123" "hello" "world")
user:
Response: Function input - output pairs: (abc, jqy) (123, ) (hello, cbdda) (world, lawdo) 

assistant:
Interesting. Let's try some more test cases to better understand the function's behavior.

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "y" "z" "1" "2" "3" "9")
user:
Response: Function input - output pairs: (a, j) (b, q) (c, y) (y, f) (z, n) (1, ) (2, ) (3, ) (9, ) 

assistant:
Thank you. Let's test the function with upper case letters, special characters, and empty string as well.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "Y" "Z" "@" "#" "$" "%")
user:
Response: Function input - output pairs: (A, j) (B, q) (C, y) (Y, f) (Z, n) (@, @) (#, #) ($, $) (%, %) 

assistant:
Based on the test results, I can provide a description of the function:

[DESCRIPTION]: The function takes a single character as input and, if it's a lowercase or uppercase letter, it adds 9 to its ASCII value, wrapping from 'z'/'Z' back to 'a'/'A'. Numerical characters are ignored, and special characters remain unchanged.

[CODE]: Here is a Python code implementation that mimics the behavior of the function:

```python
def approximate_function(input_string):
    output_string = ""
    for character in input_string:
        if (65 <= ord(character) <= 90) or (97 <= ord(character) <= 122):
            new_character = chr((ord(character) + 9 - 65) % 26 + 65) if character.isupper() else chr((ord(character) + 9 - 97) % 26 + 97)
            output_string += new_character
        elif not character.isdigit():
            output_string += character
    return output_string
```
