how to make chatbot in python

Now that we have our training data, we can build the AI model that will learn from the data and be able to answer questions. We’ll be using a neural network, which is a type of machine learning algorithm that is modeled after the human brain. They can also be used in games to provide hints or walkthroughs. This is where the chatbot becomes intelligent and not just a scripted bot that will be ready to handle any test thrown at them. The main package that we will be using in our code here is the Transformers package provided by HuggingFace. This tool is popular amongst developers as it provides tools that are pre-trained and ready to work with a variety of NLP tasks.

Here, we will be using GTTS or Google Text to Speech library to save mp3 files on the file system which can be easily played back. With increased responses, the accuracy of the chatbot also increases. You can add as many keywords/phrases/sentences and intents as you want to make sure your chatbot is robust when talking to an actual human. The bot will be able to respond to greetings (Hi, Hello etc.) and will be able to answer questions about the bank’s hours of operation. You can imagine that training your chatbot with more input data, particularly more relevant data, will produce better results. All of this data would interfere with the output of your chatbot and would certainly make it sound much less conversational.

There are still plenty of models to test and many datasets with which to fine-tune your model for your specific tasks. As we can see, our bot can generate a few logical responses, but it actually can’t keep up the conversation. Let’s make some improvements to the code to make our bot smarter. The main idea of this model is to pass the most important data from the text that’s being processed to the next layers for the network to learn and improve.

ChatterBot provides a way to install the library as a Django app. As a next step, you could integrate ChatterBot in your Django project and deploy it as a web app. If you scroll further down the conversation file, you’ll find lines that aren’t real messages. Because you didn’t include media files in the chat export, WhatsApp replaced these files with the text . Once you’ve clicked on Export chat, you need to decide whether or not to include media, such as photos or audio messages. Because your chatbot is only dealing with text, select WITHOUT MEDIA.

It seemed fine, until a few hours later when it started turning blue and the pain became immense. What I’m gonna do is remove that print out as well as incorporate this user input so that we can terminate the loop. So if user input equals Q, we are going to exit this program. To do that, we’re gonna type messages.append, and we are gonna pass the last message that we received. So in this manner, we are expanding our conversation as it progresses. To give you an idea of what this looks like, I’m going to be printing these messages on the screen.

Eventually, you’ll use cleaner as a module and import the functionality directly into But while you’re developing the script, it’s helpful to inspect intermediate outputs, for example with a print() call, as shown in line 18. A fork might also come with additional installation instructions.

It then picks a reply to the statement that’s closest to the input string. ChatterBot uses the default SQLStorageAdapter and creates a SQLite file database unless you specify a different storage adapter. Running these commands in your terminal application installs ChatterBot and its dependencies into a new Python virtual environment. You should be able to run the project on Ubuntu Linux with a variety of Python versions. However, if you bump into any issues, then you can try to install Python 3.7.9, for example using pyenv.


We have also included another parameter named ‘logic_adapters’ that specifies the adapters utilized to train the chatbot. Fundamentally, the chatbot utilizing Python is designed and programmed to take in the data we provide and then analyze it using the complex algorithms for Artificial Intelligence. It then delivers us either a written response or a verbal one.

  • The more keywords you have, the better your chatbot will perform.
  • As simply as we all know that the Siri, Alexa, and Duolingo are some real-world examples of chatbots.
  • If your data comes from elsewhere, then you can adapt the steps to fit your specific text format.
  • When developing Angular applications, data management can quickly become complex and chaotic.
  • If you have got any questions on NLP chatbots development, we are here to help.
  • Let’s have a look at the core fields of Natural Language Processing.

We have already installed the flask in the system, so we will import the python methods we require to run the flask microserver. First of all, we will install the flask library in our system using the below command. That’s the last bit of code you will write in our tutorial. Now we can progress to the last step, launching our app on Heroku. In other words, we need to tell Flask what to do when a specific address is called.

How do chatbots work?

Let us have a quick glance at Python’s ChatterBot to create our bot. ChatterBot is a Python library built based on machine learning with an inbuilt conversational dialog flow and training engine. The bot created using this library will get trained automatically with the response it gets from the user.

Now let’s run the whole code and see what our chatbot responds to. You guys can refer to chatterbot official documents for more information, or you can see the GitHub code of it. Also, you can see the below chatbot flowchart to understand better how chatterbot works. The intuitive way to make this function to work is that we will call it every second, so that it checks whether a new message has arrived, but we won’t be doing that. Hi everyone, in this article, we will send a string, image, and document messages to Telegram using Python. We import the necessary packages for our chatbot and initialize the variables we will use in our Python project.

For example, for hunting, hunter, hunts and hunted, the lemmatize function of the WordNetLemmatizer() class will give “hunt” because it is the root word. First, we’ll train the Chatbot model, and then in section two, we’ll learn how to make it work and respond to various inputs by the user. You can manually make requests via the getUpdates method.

How to build a NLP chatbot?

  1. Select a Development Platform: Choose a platform such as Dialogflow, Botkit, or Rasa to build the chatbot.
  2. Implement the NLP Techniques: Use the selected platform and the NLP techniques to implement the chatbot.
  3. Train the Chatbot: Use the pre-processed data to train the chatbot.

Now, you can follow along or make modifications to create your own chatbot or virtual assistant to integrate into your business, project, or your app support functions. Thanks for reading and hope you have fun recreating this project. In this Python web-based project with source code, we are going to build a chatbot using deep learning and flask techniques. The chatbot will be trained on the dataset which contains categories (intents), pattern and responses. We use a special artificial neural network (ANN) to classify which category the user’s message belongs to and then we will give a random response from the list of responses. In systems, chatbots are used for a variety of reasons, including customer support, request routing, and information collection.
