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 the function on some test inputs to see its behavior.

COMMAND: PYTHON(./temp/function.py 'apple' 'banana' 'hello' 'world')
user:
Response: Function input - output pairs: (apple, roofs) (banana, irtrtr) (hello, wsffy) (world, gyhfa) 

assistant:
Interesting, let's try some more examples to understand the pattern.

COMMAND: PYTHON(./temp/function.py 'test' 'abc' 'xyz' 'sample' 'python')
user:
Response: Function input - output pairs: (test, esde) (abc, rik) (xyz, cpu) (sample, drmofs) (python, opewyt) 

assistant:
Thank you for the response. Let's try some more examples with different string lengths and character repetition.

COMMAND: PYTHON(./temp/function.py 'a' 'bb' 'ccc' 'dddd' 'eeeee' '12345' '!@#$%')
user:
Response: Function input - output pairs: (a, r) (bb, ii) (ccc, kkk) (dddd, aaaa) (eeeee, sssss) (12345, 12345) (!@#$%, !@#$%) 

assistant:
Based on the provided input-output pairs, it seems that the function implemented in ./temp/function.py is shifting each character forward in the alphabet by a fixed number of positions, wrapping around the alphabet if necessary. This is similar to a Ceasar cipher operation. However, it keeps digits and special characters unchanged.

[DESCRIPTION]: The function shifts each character in the input string forward in the alphabet by a certain number of positions (appears to be 1 position so far), wrapping around the alphabet if necessary. The function keeps digits and special characters unchanged.

[CODE]: Here's a Python code snippet that approximates the behavior of the function:

```python
def approx_function(s: str) -> str:
    shifted_string = ""
    for char in s:
        if char.isalpha():
            shift = 1
            if char.islower():
                shifted_string += chr(((ord(char) + shift - 97) % 26) + 97)
            else:
                shifted_string += chr(((ord(char) + shift - 65) % 26) + 65)
        else:
            shifted_string += char
    return shifted_string
```

To confirm the behavior, let's run the function again on a more comprehensive test set.

COMMAND: PYTHON(./temp/function.py 'alphabet' 'HELLO' 'MiXeDcAsE' '%^&*()[]')
