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 calling the function with some initial inputs to see its behavior:

COMMAND: PYTHON(./temp/function.py "a" "b" "c" "1" "2" "3")
user:
Response: Function input - output pairs: (a, Vne) (b, [wo) (c, [hree) (1, aero) (2, aero) (3, aero) 

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

COMMAND: PYTHON(./temp/function.py "aa" "ab" "ac" "aaa" "aba" "abc" "111" "12" "123" "1234")
user:
Response: Function input - output pairs: (aa, Vne) (ab, [wo) (ac, [hree) (aaa, Vne) (aba, [wo) (abc, [wo) (111, aero) (12, aero) (123, aero) (1234, aero) 

assistant:
Let's test the function with some more inputs including uppercase letters, special characters and empty string:

COMMAND: PYTHON(./temp/function.py "A" "B" "C" "!@#" " " "")
user:
Response: Error occurred, please try again (some of the input values might be undefined)
assistant:
It seems that not all input types are supported by the function. Let's test with just uppercase words and space.

COMMAND: PYTHON(./temp/function.py "A" "B" "C" " ")
user:
Response: Function input - output pairs: (A, Vne) (B, [wo) (C, [hree) ( , aero) 

assistant:
Based on the observed input-output pairs, I can describe the function as follows:

[DESCRIPTION]: The function appears to return the word for x+1 where x is the ASCII value of the input character. If the input is a digit, it returns 'aero'. If the input is a space, it also returns 'aero'.

[CODE]:
```python
def approx_function(input_string):
    if input_string.isalpha():
        return chr(ord(input_string) + 1)
    elif input_string == " ":
        return "aero"
    elif input_string.isdigit():
        return "aero"
    else:
        return "Error"
```
