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

You can create a simple chatbot in Python that implements a decision tree to determine if an object is recyclable. Below is an example of how such a chatbot could be structured. This chatbot uses a series of questions and based on the user's responses, it makes a determination on whether an object is recyclable or not.

class RecyclableChatbot:
    def __init__(self):
        self.is_recyclable = None

    def start_chat(self):
        print("Welcome! I'm here to help you determine if an object is recyclable.")
        
        # Step 1: Gather information about the object
        self.material_type = input("What is the material of the object? (e.g., plastic, paper, glass, metal): ").strip().lower()
        
        # Decision tree logic
        self.check_recyclability()

        # Step 3: Provide the result
        if self.is_recyclable:
            print("Great! The object is recyclable.")
        else:
            print("Sorry! The object is not recyclable.")

    def check_recyclability(self):
        if self.material_type == "plastic":
            self.check_plastic_type()
        elif self.material_type == "paper":
            self.check_paper_condition()
        elif self.material_type == "glass":
            self.is_recyclable = True  # Glass is usually recyclable
        elif self.material_type == "metal":
            self.is_recyclable = True  # Metal is usually recyclable
        else:
            print("Sorry, I don't recognize that material.")

    def check_plastic_type(self):
        plastic_type = input("Is it a type 1 (PETE) or type 2 (HDPE) plastic? (yes/no): ").strip().lower()
        if plastic_type == "yes":
            self.is_recyclable = True
        else:
            self.is_recyclable = False

    def check_paper_condition(self):
        paper_condition = input("Is the paper clean and dry? (yes/no): ").strip().lower()
        if paper_condition == "yes":
            self.is_recyclable = True
        else:
            self.is_recyclable = False


# Create an instance of the chatbot and start the conversation
chatbot = RecyclableChatbot()
chatbot.start_chat()

How It Works:

  1. Initialization: The RecyclableChatbot class is initialized and contains methods to handle the user interaction.
  2. Starting the Chat: The start_chat method begins the conversation, asking for the material type of the object.
  3. Decision Logic: The program calls the check_recyclability method to assess the type of material and applies a decision tree based on the material type.
    • For plastic, it checks whether it's type 1 (PETE) or type 2 (HDPE).
    • For paper, it checks if the paper is clean and dry.
    • Glass and metal are assumed to be recyclable by default.
  4. Providing Result: It then outputs whether the object is recyclable or not based on the responses.

Running the Chatbot:

To use the chatbot, simply run the above code in a Python environment. The bot will prompt for input and provide feedback based on the user's answers.
