Code for chatbot in python

Creating a chatbot in Python can be done using various libraries and frameworks. One of the most popular and easy-to-use libraries for creating chatbots is ChatterBot. Here’s a step-by-step guide to create a simple chatbot using the ChatterBot library.

Step 1: Install ChatterBot

First, you need to install the ChatterBot library. You can do this using pip:

pip install chatterbot
pip install chatterbot_corpus

Step 2: Create a Chatbot

Next, you can create a simple chatbot using the following code:

from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
# Create a new instance of a ChatBot
chatbot = ChatBot('MenlypediaBot')
# Create a new trainer for the chatbot
trainer = ChatterBotCorpusTrainer(chatbot)
# Train the chatbot based on the english corpus
trainer.train('chatterbot.corpus.english')
# Get a response to an input statement
response = chatbot.get_response('Hello, how are you today?')
print(response)

Step 3: Enhancing the Chatbot

You can further enhance the chatbot by adding more training data and customizing responses. Here’s how you can do it:

from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer
# Create a new instance of a ChatBot
chatbot = ChatBot('MenlypediaBot')
# Create a new trainer for the chatbot
trainer = ListTrainer(chatbot)
# Train the chatbot with a few custom conversations
trainer.train([
    "Hi, how can I help you?",
    "I need assistance with my homework.",
    "Sure, I can help you with that. What subject are you working on?",
    "I am working on a history project.",
    "That's great! History is fascinating. What specifically are you studying?",
    "I am studying ancient Egypt.",
    "Ancient Egypt is indeed very interesting. Do you need help with any specific part?"
])
# Get a response to an input statement
response = chatbot.get_response('I am studying ancient Egypt.')
print(response)

Step 4: Implementing a Chat Interface

To interact with your chatbot, you can create a simple text-based interface:

from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer
# Create a new instance of a ChatBot
chatbot = ChatBot('MenlypediaBot')
# Create a new trainer for the chatbot
trainer = ListTrainer(chatbot)
# Train the chatbot with a few custom conversations
trainer.train([
    "Hi, how can I help you?",
    "I need assistance with my homework.",
    "Sure, I can help you with that. What subject are you working on?",
    "I am working on a history project.",
    "That's great! History is fascinating. What specifically are you studying?",
    "I am studying ancient Egypt.",
    "Ancient Egypt is indeed very interesting. Do you need help with any specific part?"
])
print("ChatBot: Hello! How can I assist you today?")
while True:
    try:
        user_input = input("You: ")
        if user_input.lower() == 'exit':
            print("ChatBot: Goodbye!")
            break
        response = chatbot.get_response(user_input)
        print("ChatBot:", response)
    except(KeyboardInterrupt, EOFError, SystemExit):
        break
