Challenge: Basic Smores Recipe
Task
Swipe to start coding
When you run this script, it should output the layers of a smore in the correct order: cracker, chocolate, marshmallow, cracker.
This exercise demonstrates the concept of how decorators wrap functionality around a function in Python.
- In the wrapper function of the
crackersdecorator, you need to call the function being decorated (i.e.,func). This should be done between the two print statements; - Ensure that the function func is called with any arguments and keyword arguments it might receive;
- Similar to the crackers decorator, the chocolate decorator should call the function it's decorating.
- The main task is to put decorators in right sequence. You must receive:
python91234~~cracker~~-roasted-------marshmallow-=chocolate=~~cracker~~
