Alienbot Project - stuck in no_match_intent function

https://www.codecademy.com/paths/build-chatbots-with-python/tracks/rule-based-chatbots/modules/rule-based-chatbots/projects/python-chatbot-alienbot

Hi all, I have a few versions of this Alienbot from in my class that I’m trying to get running. In this particular one, the program is stuck in the no_match_intent function. Typing “exit” as input on one of the alienbot’s questions will stop the program successfully, but otherwise it never proceeds from that function.

import re
import random

class AlienBot:
  # potential negative responses
  negative_responses = ("no", "nope", "nah", "naw", "not a chance", "sorry")
  # keywords for exiting the conversation
  exit_commands = ("quit", "pause", "exit", "goodbye", "bye", "later")
  # random starter questions
  random_questions = (
    "Why are you here? ",
    "Are there many humans like you? ",
    "What do you consume for sustenance? ",
    "Is there intelligent life on this planet? ",
    "Does Earth have a leader? ",
    "What planets have you visited? ",
    "What technology do you have on this planet? "
  )

if your answer was not match to those regex, it would definately return strings from no_match_intent function…

I’ve fixed and optimized your code with explanations for learning purposes:

  1. Using a Dictionary to Store Responses: We can use a dictionary to store responses for each intent, making the code more organized and easier to maintain.

  2. Refactor make_exit Function: We can refactor the make_exit function to simplify the exit command checking.

  3. Refactor match_reply Function: Instead of repeatedly checking found_match and intent in separate if statements, we can directly return the response associated with the intent once it’s found.

  4. Consistent Input Handling: Ensure consistent handling of user input by converting it to lowercase.

Here’s the code with these fixes:

import re
import random

class AlienBot:
    def __init__(self):
        self.name = None
        self.alienbabble = {
            'describe_planet_intent': r'.*(how|tell.*about|interest.*in).*your.*planet',
            'answer_why_intent': r'why are you.*(here|asking me?\s?so?\s?many questions)\??',
            'cubed_intent': r'can.*you.*cube.*number (\d+)?',
            'alien_interest_intent': r'what.*about.*you\??'
        }

        self.responses = {
            'describe_planet_intent': [
                "My planet is a utopia of diverse organisms and species.",
                "I am from Opidipus, the capital of the Wayward Galaxies."
            ],
            'answer_why_intent': [
                "I come in peace.",
                "I am here to collect data on your planet and its inhabitants.",
                "I heard the coffee is good."
            ],
            'alien_interest_intent': [
                "I don't like talking about myself",
                "I'd like to keep that to me.",
                "Sorry, you are asking for too much information."
            ]
        }

    def greet(self):

        will_help = input(f"Hi {self.name}, I'm Etcetera. I'm not from this planet. Will you help me learn about this planet? ").lower()

        if will help in self.negative_responses:
            print("Ok, have a nice Earth day!")
        else:
            self.chat()

    def make_exit(self, reply):
        for exit_command in self.exit_commands:
            if exit_command in reply:
                print("Ok, have a nice day!")
                return True
        return False

    def chat(self):
        reply = input(random.choice(self.random_questions)).lower()
        while not self.make_exit(reply):
            reply = input(self.match_reply(reply)).lower()

    def match_reply(self, reply):
        for intent, regex_pattern in self.alienbabble.items():
            found_match = re.match(regex_pattern, reply)
            if found_match:
                return random.choice(self.responses.get(intent, self.no_match_intent()))

        return self.no_match_intent()

    def describe_planet_intent(self):
        responses = self.responses['describe_planet_intent']
        return random.choice(responses)

    def answer_why_intent(self):

        return random.choice(responses)

    def cubed_intent(self, number):
        number = int(number)
        return f"The cube of {number} is {number**3}. Isn't that cool?"

    def no_match_intent(self):
        responses = ["Please, tell me more.", "Tell me more!", "Why do you say that?"]
        return random.choice(responses)

    def alien_interest_intent(self):
        responses = self.responses['alien_interest_intent']
        return random.choice(responses)

# Create an instance of AlienBot

Alienbot.greet()

I’ve made these fixes and optimizations to make the code more organized and functional. This code should work correctly and efficiently for your AlienBot program.
