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 begin by testing the function with different inputs. 

COMMAND: PYTHON(./temp/function.py "apple" "banana" "orange")
user:
Response: Function input - output pairs: (apple, tmmrw) (banana, dtqtqt) (orange, bktqfw) 

assistant:
Let's test the function with some more inputs.

COMMAND: PYTHON(./temp/function.py "hello" "world" "python" "programming")
user:
Response: Function input - output pairs: (hello, jwrrb) (world, ubkre) (python, mzajbq) (programming, mkbfktvvgqf) 

assistant:
Let's continue testing the function with more inputs, including inputs with uppercase characters.

COMMAND: PYTHON(./temp/function.py "CaSe" "NUM123" "1fish" "@!$#@#$#")
user:
Response: Function input - output pairs: (CaSe, otiw) (NUM123, qcv123) (1fish, 1ngij) (@!0@#0, @!0@#0) 

assistant:
Based on the provided input-output pairs, it seems that the function is transforming each character in the input string based on its ASCII code. Specifically, it appears to add 2 to the ASCII value of each character, except for numbers and special characters, which remain unchanged.

[DESCRIPTION]: The function takes a string input, adds 2 to the ASCII value of each character (excluding numbers and special characters), and returns the transformed string.

[CODE]:
```python
def approx_function(input_string):
    output_string = ''
    for char in input_string:
        if char.isalpha():
            output_string += chr(((ord(char) - 65 + 2) % 26) + 65) if char.isupper() else chr(((ord(char) - 97 + 2) % 26) + 97)
        else:
            output_string += char
    return output_string
```
Please note that this code is an approximation of the function's behavior based on the observed input-output pairs, and there might be subtle differences in the actual implementation.
