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 interpreting the function, I will call f(x) with some example input strings. 

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "function" "input")
user:
Response: Function input - output pairs: (hello, zw9ddg) (world, og9jdv) (test, lw9kl) (function, xmfu9lagf) (input, af9hml) 

assistant:
Let's test the function with more input strings and some edge cases to get a better understanding of the function's behavior.

COMMAND: PYTHON(./temp/function.py "a" "A" "abc" "123" "!" "&*()")
user:
Response: Function input - output pairs: (a, 9s) (A, 9S) (abc, s9tu) (123, 1923) (!, 9!) (&*(), &*9()) 

assistant:
Based on the given input-output pairs, I can see a pattern forming. Let me run one more test to confirm my hypothesis.

COMMAND: PYTHON(./temp/function.py "example" "Function" "Test123")
user:
Response: Function input - output pairs: (example, wps9ehdw) (Function, Xmfu9lagf) (Test123, Lwk9l123) 

assistant:
From the given input-output pairs, I can infer the following behavior of the function:

[DESCRIPTION]: The function takes a string input and iterates over each character. If the character is an uppercase or lowercase alphabetic character, its Unicode code point is incremented by 12. If the character is a numeric character, it remains unchanged. After processing each character, it appends the string '9' at the end of every alphabetic character (uppercase or lowercase) as a suffix.

[CODE]:
```python
def approx_function(input_string):
    output = ""
    for char in input_string:
        if char.isalpha():
            shifted_char = chr((ord(char) - 65 + 12) % 26 + 65) if char.isupper() else chr((ord(char) - 97 + 12) % 26 + 97)
            output += shifted_char + "9"
        elif char.isdigit():
            output += char
        else:
            output += char + "9"
    return output
```
Note that this is an approximation and may not completely match the behavior of the original function.
