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 sample inputs.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "hello" "world")
user:
Response: Function input - output pairs: (apple, Fuuqj) (banana, Hgtgtg) (hello, Mjqqt) (world, Btwqi) 

assistant:
Thank you for providing the output. Let's test some more inputs to see if we can identify a pattern.

COMMAND: PYTHON(./temp/function.py "abc" "def" "ghi" "jkl" "mno" "pqr" "stu" "vw" "xyz")
user:
Response: Function input - output pairs: (abc, Def) (def, Ghi) (ghi, Jkl) (jkl, Mno) (mno, Pqr) (pqr, Stu) (stu, Vwx) (vw, Xy) (xyz, Abc) 

assistant:
Based on the provided input-output pairs, it seems like the function is shifting each character in the input string forward by two positions in the alphabet, and wrapping around at 'z'. Let's verify this with a few more tests.

COMMAND: PYTHON(./temp/function.py "shift" "rotate" "example" "YZ")
user:
Response: Function input - output pairs: (shift, Xmnky) (rotate, Xuzgzk) (example, Lehtwsl) (YZ, Ab) 

assistant:
[DESCRIPTION]: The function is shifting each character in the input string forward by two positions in the alphabet, and wraps around at 'z' to continue from 'a'.

[CODE]:
```python
def approximate_function(input_string):
    output_string = ""
    for char in input_string:
        if char.isalpha():
            shifted_char = chr(((ord(char.lower()) - ord('a') + 2) % 26) + ord('a'))
            if char.isupper():
                output_string += shifted_char.upper()
            else:
                output_string += shifted_char
        else:
            output_string += char
    return output_string
```
