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, let's test the function with some inputs. 

COMMAND: PYTHON(./temp/function.py "Hello" "world" "test" "example")
user:
Response: Function input - output pairs: (Hello, HeLlO) (world, WoRlD) (test, TeSt) (example, ExAmPlE) 

assistant:
Thank you for the response. I have an idea of what the function is doing, but let's test it with a few more inputs.

COMMAND: PYTHON(./temp/function.py "interesting" "Advanced" "PYTHON" "functions")
user:
Response: Function input - output pairs: (interesting, InTeRlStInG) (Advanced, AdVaNjEd) (PYTHON, PyThOn) (functions, FuNcTpOnS) 

assistant:
Based on the given input-output pairs, I can provide an approximate description and implementation of the function f(x).

[DESCRIPTION]: The function takes a string as input and alternates the case of the letters in the string. Starts by capitalizing the first letter, leaving the second letter lowercase, capitalizing the third letter, and so on. 

[CODE]: 
```python
def f(x):
    result = ''
    for i, c in enumerate(x):
        if i % 2 == 0:
            result += c.upper()
        else:
            result += c.lower()
    return result
```

Let's test the function some more to make sure it works consistently.

COMMAND: PYTHON(./temp/function.py "additional" "tests" "just" "to" "Be" "sure")
