You might be surprised at how often we interact with chatbots without even realizing it. You’ve used one of the above chatbot once in a while.

Now, let’s build your very own chatbot using Python! We’ll design a virtual assistant that is specifically yours using straightforward steps and creative flair.

To execute our code, we’ll utilize Jupyter Notebook. Get ready to unleash Python’s magic as you experience the interesting world of conversational AI. Let’s begin; it’s going to be a great journey!


To begin with this project, it’s crucial to have a basic understanding of Python programming and some knowledge of regular expressions and manipulating strings.

Setting Up the Environment

To build our chatbot, we’ll be using Python, so make sure you have Python installed on your system. You can download and install Python from the official website. Additionally, we’ll be using the re (regular expression) module, which comes with Python by default.

Defining the Basic Structure

Let’s start by setting up the basic structure of our chatbot. Open a new Python file and define the function get_response(user_input) that will generate responses based on the user input.

import random

def get_response(user_input):
    # Convert user input to lowercase
    user_input = user_input.lower()

Creating Responses

Now, we’ll define the responses for the chatbot based on different user inputs. For this guide, we’ll keep it simple and include only 12 questions that the chatbot can respond to. Feel free to add more responses and customize the answers to your liking.

    # Define some basic responses
    greetings = ['hello', 'hi', 'hey', 'howdy']

    questions = ['how are you?', 'what is your name?', 'what can you do?', 'tell me a joke', 'who created you?', 'what is the weather like today?', 'how can I contact customer support?', 'what time is it?', 'where are you located?', 'how do I reset my password?', 'what are your working hours?', 'tell me a fun fact']

    jokes = ["Why don't scientists trust atoms? Because they make up everything!", "Why did the scarecrow win an award? Because he was outstanding in his field!", "Why did the bicycle fall over? It was two-tired!"]

    weather = ["Today is sunny and warm.", "Expect a few clouds and a slight chance of rain.", "It's going to be a hot day."]

Handling User Input

Now, let’s complete the get_response function by handling different user inputs and generating appropriate responses.

    # Generate responses based on user input
    if any(greeting in user_input for greeting in greetings):
        return random.choice(['Hello!', 'Hi!', 'Hey there!', 'Hi, how can I assist you?'])

    elif any(question in user_input for question in questions):
        if 'name' in user_input:
            return "My name is Chatbot."
        elif 'do' in user_input and 'you' in user_input:
            return "I am a simple chatbot. I can respond to basic questions and tell jokes."
        elif 'joke' in user_input:
            return random.choice(jokes)
        elif 'weather' in user_input:
            return random.choice(weather)
        # Add more responses for other questions

        return "I'm sorry, I didn't understand that. Can you please rephrase your question?"

Putting It All Together

Now that we have defined the get_response function, let’s create a main loop to interact with our chatbot.

def main():
    print("Chatbot: Hi, I'm your friendly chatbot. Ask me anything or say hello!")

    while True:
        user_input = input("You: ")
        response = get_response(user_input)
        print("Chatbot:", response)

if __name__ == "__main__":

Test Your Chatbot

Run your Python script, and you’ll have your chatbot up and running! Interact with it by typing messages and questions in the console. The chatbot will respond based on the predefined responses.

This code is for creating a simple chatbot using Python. A chatbot is like a virtual assistant that can talk to you and answer your questions.

The chatbot has different responses for different types of inputs. For example, if you say “hello,” it might respond with “Hi there!” or “Hello!” It can also tell you jokes, give you weather updates, or provide support information.

When you run the code, the chatbot will greet you and wait for your input. You can type your questions or messages, and the chatbot will respond based on what you said.

It’s a fun way to explore how chatbots work and get started with coding in Python! Feel free to try it out and have a conversation with your new virtual friend!


What exactly is a chatbot, and how does it work in this project?

In this project, a chatbot is a virtual assistant designed to have conversations with users. It responds to your messages and questions based on pre-defined rules we’ve set up in the code. When you type something, the chatbot uses Python to understand your input and provide a suitable response.

Can I talk to the chatbot about anything, or are there specific topics it understands?

While the chatbot is programmed to handle various scenarios like greetings, answering basic questions, telling jokes, providing weather updates, offering customer support information, and sharing fun facts, it is limited to those specific responses. It won’t understand complex or unrelated queries.

How do I try out this chatbot on my computer?

It’s easy! All you need is Python installed on your computer. Download the code and run it in a Python environment. Once you execute the script, the chatbot will introduce itself and be ready to chat with you.

Can I make the chatbot smarter and add more interactions?

Absolutely! This chatbot is just a starting point. As you progress in your coding journey, you can enhance its abilities. Explore advanced Natural Language Processing (NLP) techniques, experiment with machine learning models, and integrate external APIs to provide real-time data. The sky’s the limit!

What’s the potential of chatbots in the real world, and how can I learn more about them?

Chatbots are revolutionizing various industries, making customer support, e-commerce, healthcare, finance, and other areas more efficient. To learn more, you can explore online resources, take courses on NLP and AI, and join developer communities to stay up-to-date with the latest advancements in chatbot technology.


We’ve successfully created a simple chatbot using Python! 💃 This little virtual assistant responds to specific questions and messages according to what we’ve programmed it to say.

It may seem limited, but building this chatbot is an exciting first step for beginners to understand how chatbots work. We’ve learned how to make the chatbot respond to greetings, answer basic questions, tell jokes, and even provide weather updates and fun facts.
