You can run the chatbot.ipynb which also includes step by step instructions. Natural Language Processing with Python provides a practical introduction to programming for language processing. To ensure that all the prerequisites are installed, run the following command in the terminal.

This project may serve as a great starting point for developing more advanced chatbots or integrating chatbot functionality into your applications. 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. The first step is to create rules that will be used to train the chatbot.

Types of chatbots

We will use a ChatterBot library that features ML-based algorithms to generate meaningful responses to users’ requests. Go through these steps to develop a Python-based chatbot from scratch. Let’s look at a simple example of a chatbot that the Dataсamp training platform describes in its tutorials.

At the same time, we must also provide it with enough information so that it can do its job properly informed. As you know, a language generation model does not always give the same answers to the same inputs. The lower the value of temperature, the more similar the result will be for the same inputs, even repeating itself in many cases. Now we are going to define two functions, which will be the ones that will contain the logic of maintaining the memory of the conversation. We will have to organize it better, so we don’t have to write code every time the user adds new phrases.


We have covered the NLTK library later on where we discuss how it is useful for creating chatbots. In today’s world, we have libraries that specialize in understanding human language. Python’s NLTK library provides the necessary means to connect with machines and make them understand the intent of humans and reply accordingly. To set the storage adapter, we will assign it to the import path of the storage we’d like to use.

The bot created using this library will get trained automatically with the response it gets from the user. This article consists of a detailed python chatbot tutorial to help you easily build an AI chatbot chatbot using Python. In this python chatbot tutorial, we’ll use exciting NLP libraries and learn how to make a chatbot from scratch in Python.

It is a simple chatbot example to give you a general idea of making a chatbot with Python. With further training, this chatbot can achieve better conversational skills and output more relevant answers. Running a test will check Kavana’s bot conversational skills. Call the ‘get_responses()’ method of the ‘Chatbot’ instance.

  • This means that these chatbots instead utilize a tree-like flow which is pre-defined to get to the problem resolution.
  • Within Chatterbot, training becomes an easy step that comes down to providing a conversation into the chatbot database.
  • The ultimate objective of NLP is to read, decipher, understand, and make sense of human language in a valuable way.
  • You want to extract the name of the city from the user’s statement.

At that time, the bot will not answer any questions, but another function is forward. And, the following you on how to complete this task. Let us now explore step by step and unravel the answer of how to create a chatbot in Python. Consider an input vector that has been passed to the network and say, we know that it belongs to class A. Assume the output layer gives the highest value for class B.


This tutorial does not require foreknowledge of natural language processing. NLTK comes with a module known as “” It simplifies chatbot creation. All you need to do is utilize the framework and the dataset and build a chatbot using it. Right now, there are plenty of online tutorials you can follow.

By following these steps, you’ll have a functional Python AI chatbot that you can integrate into a web application. This lays down the foundation for more complex and customized chatbots, where your imagination is the limit. Experiment with different training sets, algorithms, and integrations to create a chatbot that fits your unique needs and demands. Natural Language Processing, often abbreviated as NLP, is the cornerstone of any intelligent chatbot.

Artificial Intelligence is a field that is proving to be very healthy and productive in various areas. A Chatbot is one of its results that allows humans to get their answers through bots. It is one of the successful strategies to grab customers’ attention and provide them with the most impactful output. You will learn about the origin and history of chatbots, their types and applications, their architecture, and their mechanism. You will also gain practical skills through the hands-on demo on building chatbots using Python. The most popular applications for chatbots are online customer support and service.
