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.

To start with the experiment, let's run the function on a few input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "12345")
user:
Response: Function input - output pairs: (hello, gello) (world, vorld) (12345, 12345) 

assistant:
Let's run more tests with various input strings to understand the function better.

COMMAND: PYTHON(./temp/function.py "abcd" "zyxw" "9876" "test" "sample" "!@#$%")
user:
Response: Function input - output pairs: (abcd, zbcd) (zyxw, yyxw) (9876, 9876) (test, sest) (sample, rample) (!@#$%, !@#$%) 

assistant:
Let's run even more tests with various input strings to understand the function better.

COMMAND: PYTHON(./temp/function.py "qwerty" "uiop" "aszx" "Computer" "DATA" "Home1")
user:
Response: Function input - output pairs: (qwerty, pwerty) (uiop, tiop) (aszx, zszx) (Computer, Bomputer) (DATA, CATA) (Home1, Gome1) 

assistant:
[DESCRIPTION]: The function takes an input string and replaces the first character of the string with its adjacent character in the alphabets by incrementing its ASCII value by 1. If the first character is a non-alphabetic character (such as digits or special characters), the function returns the same character unchanged.

[CODE]: 

```python
def approx_function(input_str):
    if input_str[0].isalpha():
        next_char = chr(ord(input_str[0]) + 1)
        return next_char + input_str[1:]
    else:
        return input_str
```
