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.

Let's start by testing the function f(x) with some simple inputs. Please execute the following command:

COMMAND: PYTHON(./temp/function.py a b c 1 2 3 hello world)
user:
Response: Function input - output pairs: (a, c) (b, d) (c, e) (1, 1) (2, 2) (3, 3) (hello, nkrru) (world, cuxrj) 

assistant:
Interesting, let's test the function with additional input strings to understand its behavior better. Please execute the following command:

COMMAND: PYTHON(./temp/function.py AbC 123 !@# %20)
user:
Response: Function input - output pairs: (AbC, EfG) (123, 123) (!@#, !@#) (%20, %20) 

assistant:
Based on the results so far, the function seems to shift alphabetic characters by a certain amount. Let's test this further by trying additional inputs. Please execute the following command:

COMMAND: PYTHON(./temp/function.py ZzYy MADNESS dancE CraZy1)
user:
Response: Function input - output pairs: (ZzYy, EeDd) (MADNESS, UILVMAA) (dancE, jgtiK) (CraZy1, JyhGf1) 

assistant:
[DESCRIPTION]: The function shifts alphabetic characters by a fixed amount, and doesn't modify numeric and special characters. In this case, the shift appears to be +2 positions forward in the alphabet.

[CODE]:
```python
def f_approx(x):
    shifted = ''
    for char in x:
        if 'A' <= char <= 'Z':
            shifted += chr(((ord(char) - ord('A') + 2) % 26) + ord('A'))
        elif 'a' <= char <= 'z':
            shifted += chr(((ord(char) - ord('a') + 2) % 26) + ord('a'))
        else:
            shifted += char
    return shifted
```
Please note that this code is an approximation of the behavior of the original f(x) function.
