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 will begin by running a few tests on the function f(x) with different string inputs to understand its behavior.

COMMAND: PYTHON(./temp/function.py "one" "two" "three")
user:
Response: Function input - output pairs: (one, wri) (two, tyw) (three, tboii) 

assistant:
Thank you for the response. I will now test the function with some more string inputs.

COMMAND: PYTHON(./temp/function.py "test" "hello" "world" "ABCDE")
user:
Response: Function input - output pairs: (test, tigt) (hello, bihhw) (world, ywohx) (ABCDE, jzpxi) 

assistant:
Thank you for the response. I will run a few more tests with some special characters and numerical inputs.

COMMAND: PYTHON(./temp/function.py "12345" "!@#$%" "A1B2C3" "apple")
user:
Response: Function input - output pairs: (12345, 12345) (!@#$%, !@#$%) (A1B2C3, j1z2p3) (apple, jcchi) 

assistant:
[DESCRIPTION]: The function f(x) takes a string input and for each character that is an uppercase or lowercase letter, it returns the character that is 2 positions ahead in the alphabet, wrapping around if needed. It seems to leave the non-letter characters unchanged.

[CODE]: 
```python
def approximate_f(x):
    result = ""
    for char in x:
        if char.isalpha():
            if char.isupper():
                result += chr(((ord(char) - 65 + 2) % 26) + 65)
            elif char.islower():
                result += chr(((ord(char) - 97 + 2) % 26) + 97)
        else:
            result += char
    return result
```
