[UPDATE] Tools - Example Python code in unit 1 can't run

[Anto59290]

In unit one, there is this sample code:

def calculator(a: int, b: int) -> int:
    """Multiply two integers."""
    return a * b

print(calculator.to_string())

I am not sure why the last line is there, and I found it confusing:

• Using this code as is won't run (AttributeError: 'function' object has no attribute 'to_string')
• I found it unclear why some kind of conversion to string would be needed. It looks like the idea is that we can convert this code to a string object like Tool Name: calculator, Description: Multiply two integers., Arguments: a: int, b: int, Outputs: int but IMHO it lacks clarity.

The second example makes more sense, as it introduces the decorator, which (I guess) implements the to_string method.

The to_string version is is the decorator and is need to give the model a notion about which tool does it have access to. Indeed without the decorator the to_string() can't work
