Develop a simple chatbot that implements the decision tree previously discussed to determine if an object is recyclable using lists

Creating a simple chatbot that uses a decision tree to determine if an object is recyclable can be accomplished by employing Python and lists. The chatbot will guide users through a series of questions and use their responses to determine if the item is recyclable or not.

Here is a sample implementation:

class RecyclabilityChatBot:
    def __init__(self):
        self.questions = [
            "Is it made of plastic, metal, glass, paper, or cardboard? (Type 'plastic', 'metal', 'glass', 'paper', or 'cardboard')",
            "Is it clean and dry? (Type 'yes' or 'no')",
            "Is it a single-use item? (Type 'yes' or 'no')"
        ]
        self.decisions = {
            "plastic": self.plastic_recyclability,
            "metal": self.metal_recyclability,
            "glass": self.glass_recyclability,
            "paper": self.paper_recyclability,
            "cardboard": self.cardboard_recyclability
        }

    def run(self):
        print("Welcome to the Recycling ChatBot! Let's determine if your item is recyclable.")
        material = input(self.questions[0]).strip().lower()
        
        if material not in self.decisions:
            print("Sorry, I don't recognize that material.")
            return
        
        clean_dry = input(self.questions[1]).strip().lower()
        single_use = input(self.questions[2]).strip().lower()
        
        recyclable = self.decisions[material](clean_dry, single_use)
        
        if recyclable:
            print(f"{material.capitalize()} is recyclable!")
        else:
            print(f"{material.capitalize()} is not recyclable.")

    def plastic_recyclability(self, clean_dry, single_use):
        if clean_dry == 'yes':
            if single_use == 'no':
                return True  # Recyclable
            else:
                return False  # Not recyclable
        else:
            return False  # Not recyclable

    def metal_recyclability(self, clean_dry, single_use):
        if clean_dry == 'yes':
            return True  # Always recyclable
        else:
            return False  # Not recyclable

    def glass_recyclability(self, clean_dry, single_use):
        if clean_dry == 'yes':
            return True  # Always recyclable
        else:
            return False  # Not recyclable

    def paper_recyclability(self, clean_dry, single_use):
        if clean_dry == 'yes':
            return True  # Always recyclable
        else:
            return False  # Not recyclable

    def cardboard_recyclability(self, clean_dry, single_use):
        if clean_dry == 'yes':
            return True  # Always recyclable
        else:
            return False  # Not recyclable


if __name__ == "__main__":
    bot = RecyclabilityChatBot()
    bot.run()

How the Chatbot Works:

1. Initialization: The chatbot starts with a predefined list of questions about the material, cleanliness, and whether it is a single-use item.

2. Questioning:

   • The chatbot will ask the user about the material of the item.
   • Then it will ask if the item is clean and dry.
   • Finally, it will check whether the item is a single-use type.

3. Decision Making: Based on the user's responses, the chatbot will determine if the item is recyclable or not using specific decision functions for each material.

4. Output: The chatbot informs the user whether the item in question is recyclable.

Execution:

You can run this script in a Python environment. It will interactively ask for input and provide output based on the user's responses.
