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, I'll start by running some tests on the function. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "python" "12345" "test")
user:
Response: Function input - output pairs: (hello, raees) (world, xsvep) (python, kmdrsj) (12345, 12345) (test, dand) 

assistant:
Thank you. I'll try some more inputs to gather more data.

COMMAND: PYTHON(./temp/function.py "a" "A" "1" "!" "sample")
user:
Response: Function input - output pairs: (a, c) (A, c) (1, 1) (!, !) (sample, nczkea) 

assistant:
I appreciate the output. Let me try a few more inputs before attempting a description.

COMMAND: PYTHON(./temp/function.py "abc" "ABC" "123" "@#$" "mix34")
user:
Response: Function input - output pairs: (abc, cof) (ABC, cof) (123, 123) (@#$, @#$) (mix34, zhu34) 

assistant:
[DESCRIPTION]: The function appears to take a string input and for alphabetic characters, it shifts each character by two positions forward in the alphabet, regardless of the letter's case (upper or lower). For non-alphabetic characters (such as digits and symbols), it leaves them unchanged.

[CODE]: 

```python
def approximate_function(input_string):
    output_string = ""
    for char in input_string:
        if char.isalpha():
            shift = 2
            if char.islower():
                output_string += chr(((ord(char) - ord('a') + shift) % 26) + ord('a'))
            elif char.isupper():
                output_string += chr(((ord(char) - ord('A') + shift) % 26) + ord('A'))
        else:
            output_string += char
    return output_string
```
