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 input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "python" "function" "12345" "ABCDE")
user:
Response: Function input - output pairs: (hello, khoor) (world, zruog) (test, whvw) (python, sbwkrq) (function, ixqfwlrq) (12345, 12345) (ABCDE, DEFGH) 

assistant:
It seems like the function might be performing some kind of Caesar cipher, shifting the alphabetic characters by a fixed number of positions. Let's test more input strings to narrow down the exact behavior.

COMMAND: PYTHON(./temp/function.py "xyz" "XYZ" "Hi123" "aBcDe" "NOPQR" "mnopqr")
user:
Response: Function input - output pairs: (xyz, abc) (XYZ, ABC) (Hi123, Kl123) (aBcDe, dEfGh) (NOPQR, QRSTU) (mnopqr, pqrstu) 

assistant:
Based on the experiments, the function seems to perform a Caesar cipher, shifting the alphabetic characters forward by 3 positions, while leaving non-alphabetic characters unchanged. The shift is circular, meaning that the character that comes after 'z' is 'a', and the character that comes after 'Z' is 'A'.

[DESCRIPTION]: The function performs a Caesar cipher, shifting the alphabetic characters forward by 3 positions and leaving non-alphabetic characters unchanged. The shift is circular for both uppercase and lowercase characters.

[CODE]:
```python
def caesar_cipher(text, shift=3):
    result = []
    for char in text:
        if char.isalpha():
            offset = 65 if char.isupper() else 97
            result.append(chr(((ord(char) - offset + shift) % 26) + offset))
        else:
            result.append(char)
    return ''.join(result)
```
