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. 
assistant:
Alright, let's start by running some tests on the function to understand its behavior. 

COMMAND: PYTHON(./temp/function.py "test1" "test2" "test3")
user:
Response: Function input - output pairs: (test1, vaxv1) (test2, vaxv2) (test3, vaxv3) 

assistant:
Let's test some more inputs to get a better understanding of the function behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "function")
user:
Response: Function input - output pairs: (hello, tajjf) (world, pfdjr) (function, qcebvgfe) 

assistant:
I'll perform more tests with different inputs to figure out the pattern.

COMMAND: PYTHON(./temp/function.py "a" "ac" "abc" "ABCD" "AbCd")
user:
Response: Function input - output pairs: (a, o) (ac, ob) (abc, oub) (ABCD, oubr) (AbCd, oubr) 

assistant:
Based on the given input-output pairs, it appears that the function is incrementing the ASCII value of each character in the input string by a constant value (e.g., 14 or 15). Let's try more tests to confirm this.

COMMAND: PYTHON(./temp/function.py "12345" "Hello123" "Python")
user:
Response: Function input - output pairs: (12345, 12345) (Hello123, tajjf123) (Python, wnvtfe) 

assistant:
[DESCRIPTION]: The function shifts each alphabetic character in the input string by 14 positions forward in the alphabet, wrapping around from 'z' to 'a', and from 'Z' to 'A'. The case of the characters is preserved (i.e., uppercase remains uppercase and lowercase remains lowercase), and non-alphabetic characters are left unchanged.

[CODE]: 
```python
def approximate_function(input_string):
    output = ""
    for char in input_string:
        if char.isalpha():
            shift = 14
            if char.isupper():
                output += chr((((ord(char) - ord('A')) + shift) % 26) + ord('A'))
            else:
                output += chr((((ord(char) - ord('a')) + shift) % 26) + ord('a'))
        else:
            output += char
    return output
```
