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, I'll start by testing the function with an initial set of inputs to understand its behavior.

COMMAND: PYTHON(./temp/function.py "apple" "banana" "12345" "ABCDE")
user:
Response: Function input - output pairs: (apple, fuuqj) (banana, hgtgtg) (12345, 12345) (ABCDE, FGHIJ) 

assistant:
Let's test the function on a few more inputs to understand its behavior further.

COMMAND: PYTHON(./temp/function.py "hello" "world" "Python" "test123")
user:
Response: Function input - output pairs: (hello, mjqqt) (world, btwqi) (Python, irmahg) (test123, vguv123) 

assistant:
It seems the function is likely performing some kind of character shift based on the observed behavior. I will run the function on a few more inputs to be certain.

COMMAND: PYTHON(./temp/function.py "shift" "azAZ09" "!@#")
user:
Response: Function input - output pairs: (shift, xmnky) (azAZ09, utut09) (!@#, !@#) 

assistant:
[DESCRIPTION]: The function f(x) appears to take a string input and apply a character shift of 5 positions in the alphabet for both uppercase and lowercase letters. The function leaves non-alphabetic characters, such as numbers and special characters, unchanged.

[CODE]: 

```python
def f(x):
    result = ""
    for char in x:
        if 'a' <= char <= 'z':
            result += chr(((ord(char) - ord('a') + 5) % 26) + ord('a'))
        elif 'A' <= char <= 'Z':
            result += chr(((ord(char) - ord('A') + 5) % 26) + ord('A'))
        else:
            result += char
    return result
```
