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 some experiments on the function to understand its behavior.

COMMAND: PYTHON(./temp/function.py "test" "hello" "world")
user:
Response: Function input - output pairs: (test, tPts) (hello, hPPll) (world, wPdlr) 

assistant:
Interesting, let's try few more inputs to better understand the pattern.

COMMAND: PYTHON(./temp/function.py "example" "abcdefgh" "12345678")
user:
Response: Function input - output pairs: (example, PxPPlpm) (abcdefgh, PbcdhgfP) (12345678, 12348765) 

assistant:
Based on these results, it appears that the function replaces the second character with a capital P and reverses the characters in between the second character and the second-to-last character. Let's try few more inputs to confirm the pattern.

COMMAND: PYTHON(./temp/function.py "ab" "abc" "abcd" "abcde")
user:
Response: Function input - output pairs: (ab, Pb) (abc, Pcb) (abcd, Pbdc) (abcde, PbPdc) 

assistant:
[DESCRIPTION]: The function takes a string input, replaces the second character with a capital "P", and reverses the substring between the second character and the second-to-last character. The first and last characters remain unchanged.

[CODE]:
```python
def approx_function(s):
    if len(s) < 2:
        return s

    middle_substring = s[2:-1]
    middle_substring_reversed = middle_substring[::-1]

    return s[0] + "P" + middle_substring_reversed + s[-1]
```

Please note that this approximation might not cover more specific edge-cases. To get a perfect replica, we would need to analyze the original function source code.
