Hint:
Here is the general syntax for a decorator that accepts no arguments:
def decorator(decorated_function:callable): def wrapper_function(*args, **kwargs):
#this is where we make modifications to the arguments before invoking the decorated function
return_value = decorated_function(*args, **kwargs)
#this is where we make modifications to the returned value after invoking the decorated function
return return_value
return wrapper_function
def shorten_args_decorator(function:callable):
This question is meant to test your knowledge of creating a decorator to decorate a function that accepts an arbitrary number of positional and keyword arguments and alters the arguments before passing them to the decorated function. This decorator will truncate the number ofpositional arguments to 3 if the total number of positional arguments is greater then 3. The order of the positional arguments must be maintained. It will then pass the truncated form of the positional arguments to the decorated function upon invocation. This decorator will not make any modifications to the keyword arguments.
def time_out_decorator(time_out:int):
This question is meant to test your knowledge of creating a decorator that accepts arguments, to decorate a function that accepts an arbitrary number of positional and keyword arguments, and to execute code before and after the decorated function's invocation. This decorator will time the execution time of the decorated function. The decorator will be constructed with an argument known as time_out. If the total execution time of the decorated function is greater than the time_out time the decorator should raise a TimeoutError, otherwise it should return the value returned from the decorated function. time_out will be an int denoting milliseconds.
