The->int at the end of the function definition indicates that the function returns an integer. This is known as type hinting and is used to help with code readability and debugging. Please note that this feature isnot enforcedin Python and it's just used as a hint for developer and IDEs...

This approach gives us a hint of what we need to do. However, if we apply wraps (or update_wrapper, which is what wraps ends up calling) to our function, it will only have foo and bar as arguments, and its name will be displayed as old. ...

def function_name(parameter1: type, parameter2: type, ...) -> return_type: # function body 类型提示(type hint)在Python中用于增强代码可读性和跨语言移植性。尽管静态类型限定不会改变运行时行为,它可以帮助开发者明确函数参数和返回值的预期类型,提高代码质量。
