Question
Fix an error and show it please?
And here are the information about the homework and for the error too.
def kwargs_to_args_decorator(*args, **kwargs):
This question is meant to test your knowledge of creating a decorator that accepts an arbitrary number of positional and keyword arguments, 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. When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized. After performing the modifications to the arguments, the decorator should invoke the decorated function with the modified arguments and return the value of the decorated function.
Examples:
args = (96, 6, 34) kwargs = {'taco': 'showman', 'potato': 'walkway', '96': '5'}
This should raise a type error because the first positional argument is not a str.
args = ('TRZJRE6MLCDN', 10, 88, 49) kwargs = {'taco': 'Juneau', 'potato': 'conservative', 'TRZJRE6MLCDN': 'V'}
This should raise a value error because the first positional argument is greater then 10 charactures.
args = ('3I7', 'dean', 48, 'bream', 62, 'cryostat', 31, 'Bruegel', 16, 'delicatessen', 6, 'Millie', 12, 'loss', 70) kwargs = {'taco': 'Heidegger', 'potato': 'grim', '3I7': 'P'}
This should raise a type error because the positional arguments after the first value are not of type int.
args = ('BPW', -77, -71, -81, -31, -21) kwargs = {'taco': 'feeble', 'potato': 'geyser', 'BPW': 'U'}
This should raise a value error because the positional arguments after the first value are less than zero.
args = ('V', 83, 91, 17, 1, 59, 49, 86, 62, 63) kwargs = {'potato': 'virulent', 'V': 'J'}
This should raise a key error because the key 'taco' is missing in the key word arguments.
args = ('Z', 23, 20, 82, 11) kwargs = {'taco': 'Permian', 'Z': 'H'}
This should raise a key error because the key 'potato' is missing in the key word arguments.
args = ('J', 90, 83, 61, 27) kwargs = {'taco': 'imputation', 'potato': 'indolent'}
This should raise a key error because a key equal to the first positional argument, is missing in the key word arguments.
args = ('88', 56, 69, 29, 97, 79) kwargs = {'taco': 'Conant', 'potato': 'strung', '88': 90}
This should raise a key error because the value associated with the key equal to the first positional argument is not a str.
args = ('FMF', 47) kwargs = {'taco': 'gazpacho', 'potato': 'bunkmate', 'FMF': 'JYMQEC37LSLX'}
This should raise a key error because the value associated with the key equal to the first positional argument is more then 10 charactures.
args = () kwargs = {'taco': 'smuggle', 'potato': 'committeemen'}
This is valid input
args = ('BYJT', 36, 29) kwargs = {'taco': 'phosgene', 'potato': 'pastel', 'BYJT': 'C'}
This is valid input
args = ('018J',) kwargs = {'taco': 'Marx', 'potato': 'tetrafluoride', '018J': 'D'}
This is valid input
