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 string inputs. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "apple" "banana" "12345")
user:
Response: Function input - output pairs: (hello, dzwwr) (world, irbwq) (test, azha) (apple, nttwz) (banana, enmnmn) (12345, 12345) 

assistant:
Interesting. Let's try some more inputs to see the pattern.

COMMAND: PYTHON(./temp/function.py "abcdefg" "HJKL" "Spaces test" "1bcde2" "~!@#$%^")
user:
Response: Function input - output pairs: (abcdefg, nevqzxj) (HJKL, dcpw) (Spaces test, htnvzh azha) (1bcde2, 1evqz2) (~!@#$%^, ~!@#$%^) 

assistant:
Based on the tests so far, it seems that the function shifts each alphabetic character by some fixed number of positions in the alphabet while keeping the case (lowercase or uppercase) the same. Non-alphabetic characters remain unchanged.

Let's try a few more inputs to further understand the pattern.

COMMAND: PYTHON(./temp/function.py "xyzXYZ" "AaBbCc" "MmNnOo" "ZzYyXx")
user:
Response: Function input - output pairs: (xyzXYZ, klfklf) (AaBbCc, nneevv) (MmNnOo, oommrr) (ZzYyXx, ffllkk) 

assistant:
The function seems to shift each letter forward in the alphabet by 11 positions for lowercase letters and -3 positions for uppercase letters, making it a Caesar cipher with varying shifts depending on the letter case. Non-alphabetic characters are left unchanged.

[DESCRIPTION]: The function takes input strings and shifts each alphabetic character by 11 positions forward in the alphabet for lowercase letters and -3 positions backward for uppercase letters. Non-alphabetic characters remain unchanged.

[CODE]:
```python
def f(x):
    result = ""
    for char in x:
        if "a" <= char <= "z":
            result += chr(((ord(char) - ord("a") + 11) % 26) + ord("a"))
        elif "A" <= char <= "Z":
            result += chr(((ord(char) - ord("A") - 3) % 26) + ord("A"))
        else:
            result += char
    return result
```

To confirm the description and code, let's test the function again with some inputs.

COMMAND: PYTHON(./temp/function.py "python" "ChecK" "Upper" "tesT")
