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 running f(x) on a few inputs. We will try some simple words and an empty string. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "")
user:
Response: Function input - output pairs: (hello, hfqqy) (world, xyvqt) (test, rfnr) (, ) 

assistant:
Thank you for the output. Let's try some more inputs with different cases and characters.

COMMAND: PYTHON(./temp/function.py "AbCdE" "123" "!@#")
user:
Response: Function input - output pairs: (AbCdE, bdstf) (123, 123) (!@#, !@#) 

assistant:
It seems that the function processes alphabetical characters. Let's test more alphabetical strings and some repeated characters.

COMMAND: PYTHON(./temp/function.py "alphabet" "repeated" "uvwxyz" "mno")
user:
Response: Function input - output pairs: (alphabet, bqohbdfr) (repeated, vfofbrft) (uvwxyz, cmxjie) (mno, aly) 

assistant:
Based on the input-output pairs, it appears that the function is incrementing the alphabetical characters by a certain value. Let's test with some simple cases to confirm this.

COMMAND: PYTHON(./temp/function.py "a" "b" "z" "A" "B" "Z")
user:
Response: Function input - output pairs: (a, b) (b, d) (z, e) (A, b) (B, d) (Z, e) 

assistant:
Based on the observations, the function increments the characters in a cyclic manner. Here's a description and code approximation of the function:

[DESCRIPTION]: The function shifts the alphabetical characters in the input string by 1 for lowercase and 2 for uppercase letters (cyclically) keeping other characters unchanged.

[CODE]: 
```python
def approx_function(input_string):
    result = ''
    for char in input_string:
        if 'a' <= char <= 'z':
            result += chr(((ord(char) - ord('a') + 1) % 26) + ord('a'))
        elif 'A' <= char <= 'Z':
            result += chr(((ord(char) - ord('A') + 2) % 26) + ord('A')).lower()
        else:
            result += char
    return result
```

To double-check the approximated function's behavior, please run it on some sample inputs:

COMMAND: PYTHON(./temp/function.py "ShiftMeByTwo" "AaBbCc" "!@*&")
