Decorators with parameters?

Question

I have a problem with the transfer of variable \'insurance_mode\' by the decorator. I would do it by the following decorator statement:

@execute_complete_rese         


        

Answer 1

def decorator(argument):
    def real_decorator(function):
        def wrapper(*args):
            for arg in args:
                assert type(arg)==int,f'{arg} is not an interger'
            result = function(*args)
            result = result*argument
            return result
        return wrapper
    return real_decorator

Usage of the decorator

@decorator(2)
def adder(*args):
    sum=0
    for i in args:
        sum+=i
    return sum

Then the

adder(2,3)

produces

10

but

adder('hi',3)

produces

      4             for arg in args:
----> 5                 assert type(arg)==int,f'{arg} is not an interger'
      6             result = function(*args)
      7             result = result*argument

AssertionError: hi is not an interger
