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 a single input string. 

COMMAND: PYTHON(./temp/function.py "hello")
user:
Response: Function input - output pairs: (hello, nkrru) 

assistant:
Thank you for the response. Let's test the function with some more inputs.

COMMAND: PYTHON(./temp/function.py "world" "test" "python" "example" "function")
user:
Response: Function input - output pairs: (world, cuxrj) (test, zkyz) (python, veznut) (example, kdgsvrk) (function, latizout) 

assistant:
Thank you. Let's test the function with some special characters and numbers.

COMMAND: PYTHON(./temp/function.py "!@#$%^" "12345" "67890" "mixed123string" "!$tr&ng")
user:
Response: Function input - output pairs: (!@#$%^, !@#$%^) (12345, 12345) (67890, 67890) (mixed123string, sodkj123yzxotm) (!&ng, !&tm) 

assistant:
Based on the test results, it appears the function keeps numbers and special characters unchanged, while incrementing each alphabet character by 3 positions in the alphabet.

[DESCRIPTION]: The function increments each alphabet character in the input string by 3 positions in the alphabet and keeps numbers and special characters unchanged.

[CODE]: 
```python
def f_approx(x):
    result = ""
    for char in x:
        if char.isalpha():
            if char.islower():
                result += chr(((ord(char) - ord('a') + 3) % 26) + ord('a'))
            else:
                result += chr(((ord(char) - ord('A') + 3) % 26) + ord('A'))
        else:
            result += char
    return result
```

Let's run one final test for confirmation. 

COMMAND: PYTHON(./temp/function.py "Advanced" "Example123!")
