    It’s funny how Python spent the past like 6 years developing the type hinting system (which is a massive improvement from no typing don’t get me wrong) only to start re-introducing duck typing again with the Protocols.

    The one thing I’ll always love about it is the ability to override builtins and do dumb things like call ‘sum(cats)’ where cats is a list of cat objects and have it like print out meow to the terminal for each cat in the list.

    Shit like that makes it perfect for internal tools.

        Even better is to create a decorator and just wrap the offending functions:

        def shut_up(func):
            def call(*args, **kwargs):
                try:
                    return func(*args, **kwargs)
                except Exception as e:
                    print(f"shit's fucked, but I'll be quiet about it")
                    return
            return call
        
        @shut_up
        def add(x: int, y: int):
            print(x + y)
        
        add(1, 2)
        add(-1, 2)
        add(1, "2")
        
        >>> 3
        >>> 1
        >>> "shit's fucked, but I'll be quiet about it"
        

        Or if you want to attempt to salvage it:

        def shut_up(func):
            def call(*args, **kwargs):
                try:
                    return func(*args, **kwargs)
                except Exception as e:
                    try:
                        return func(*map(int, args), **kwargs)
                    except Exception as e:
                        print(f"shit's really fucked, I even tried to fix it for you")
                        return None
            return call
