Question

Develop a simple chatbot that implements the decision tree previously discussed to determine if an object is recyclable using:
1. Modular architecture
2. Appropriate libraries
3. Well named variables
4. Lists
5. Control structures

Answer 1

Here’s a basic implementation of a chatbot that uses a decision tree for determining whether an object is recyclable. We'll employ modular architecture, appropriate libraries, and well-named variables, utilize lists, and control structures. This implementation will be in Python.

### Required Libraries
In this implementation, we will use the standard library, so no additional packages are required.

### Code Implementation

```python
# Importing necessary libraries
def main():
print("Welcome to the Recycling Decision Bot!")
object_type = get_object_type()
is_recyclable = determine_recyclability(object_type)
display_result(object_type, is_recyclable)

def get_object_type():
"""Prompts the user for the type of object they want to check."""
print("What type of object would you like to check for recyclability?")
object_list = ["plastic bottle", "aluminum can", "cardboard", "glass jar", "newspaper"]
for index, item in enumerate(object_list):
print(f"{index + 1}. {item}")

object_choice = int(input("Enter the number corresponding to the object: ")) - 1
return object_list[object_choice] if 0 <= object_choice < len(object_list) else None

def determine_recyclability(object_type):
"""Determines if the object type is recyclable."""
recycling_decision_tree = {
"plastic bottle": True,
"aluminum can": True,
"cardboard": True,
"glass jar": True,
"newspaper": True,
# Add more objects and their recyclability status here
}

return recycling_decision_tree.get(object_type, False)

def display_result(object_type, is_recyclable):
"""Displays the result of the recyclability check."""
if object_type:
if is_recyclable:
print(f"Yes, a {object_type} is recyclable!")
else:
print(f"No, a {object_type} is not recyclable.")
else:
print("Invalid object type selected. Please restart the application.")

if __name__ == "__main__":
main()
```

### Explanation of the Code

1. **Modular Architecture**: The main logic of the program has been compartmentalized into functions: `main()`, `get_object_type()`, `determine_recyclability()`, and `display_result()`. Each function has a single responsibility, which fits well with modular programming principles.

2. **Appropriate Libraries**: This basic chatbot implementation doesn't require external libraries. It uses Python's built-in capabilities.

3. **Well Named Variables**: The variables and functions are named appropriately to reflect their purpose, which makes the code more readable. For example, `object_type`, `is_recyclable`, and `recycling_decision_tree`.

4. **Lists**: There’s a list that contains the types of recyclable objects (`object_list`), providing a simple way to manage the objects being checked.

5. **Control Structures**: The implementation uses control structures such as loops (for displaying options to the user) and conditionals (to check if the object is recyclable and handle user input) for decision-making.

### How to Run the Chatbot
To run the chatbot, simply copy the code into a Python environment and execute it. The bot will prompt the user to select an object and will return whether the selected object is recyclable based on a predefined decision tree.
