Simple example of a custom decorator with arguments in Python.

decorator_with_arguments.py

from collections import namedtuple

User = namedtuple('User', field_names=['username', 'role'])
current_user = User(username='Jeff', role='red')

def role_required(required_role):
    def has_role(current_user):
        return current_user.role == required_role

    def role_decorator(func):
        def function_wrapper(*args, **kwargs):
            if has_role(current_user):
                func(*args, **kwargs)
            else:
                raise Exception(f'not allowed :(. requires role <<{required_role}>>')
        return function_wrapper
    return role_decorator

@role_required('red') 
def red_zone(): 
    print('Entered red zone successfully')

@role_required('blue') 
def blue_zone(): 
    print('Entered blue zone successfully')
