Creating Chatbot Using Python Programming Language

You can train bots, automate welcome messages, and analyze incoming messages for customer segmentation, contributing to increased customer satisfaction. In this brief tutorial I’ll walk you through using a popular Python language library to construct a simple chatbot that evaluates and responds to user input. Currently, chatbots, or digital assistants, use natural language processing to communicate with humans. Known as NLP, this technology focuses on understanding how humans communicate with each other and how we can get a computer to understand and replicate that behavior.

  • If this is the case, the function returns a policy violation status and if available, the function just returns the token.
  • If you’re not interested in houseplants, then pick your own chatbot idea with unique data to use for training.
  • Then we need a file ‘intents.json’ which is the data used to train our Neural Network.
  • To interact with such chatbots, an end user has to choose a query from a given list or write their own question according to suggested rules.
  • Scripted chatbots can be used for tasks like providing basic customer support or collecting contact details.
  • Chatbots often perform tasks like making a transaction, booking a hotel, form submissions, etc.

Alternatively, you could parse the corpus files yourself using pyYAML because they’re stored as YAML files. ChatterBot uses the default SQLStorageAdapter and creates a SQLite file database unless you specify a different storage adapter. 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.

Creating ChatBot Using Natural Language Processing in Python

The only required argument is a name, and you call this one “Chatpot”. No, that’s not a typo—you’ll actually build a chatty flowerpot chatbot in this tutorial! You’ll soon notice that pots may not be the best conversation partners after all.

WebSockets are a very broad topic and we only scraped the surface here. This should however be sufficient to create multiple connections and handle messages to those connections asynchronously. /refresh_token will get the session history for the user if the connection is lost, as long as the token is still active and not expired. Next create an environment file by running touch .env in the terminal. We will define our app variables and secret variables within the .env file.

How to Work with Redis JSON

While we can use asynchronous techniques and worker pools in a more production-focused server set-up, that also won’t be enough as the number of simultaneous users grow. Imagine a scenario where the web server also creates the request to the third-party service. During the trip between the producer and the consumer, the client can send multiple messages, and these messages will be queued up and responded to in order. Once you have set up your Redis database, create a new folder in the project root named worker. FastAPI provides a Depends class to easily inject dependencies, so we don’t have to tinker with decorators. In the websocket_endpoint function, which takes a WebSocket, we add the new websocket to the connection manager and run a while True loop, to ensure that the socket stays open.


In the Train tab, create an intent called ask, and add the expression I’m interested in. Create a bot that asks the user to select an animal to get a fun fact about. As an added bonus, we will show how to deploy a Python script to SAP BTP. Special thanks to Yohei Fukuhara for his blog Create simple Flask REST API using Cloud Foundry. VS Code with the Python extension by Microsoft, though you can use any Python development environment.

The system returns a list of users, not books, sorted by keyword and precise answers to natural language. What we are doing with the JSON file is creating a bunch of messages that the user is likely to type in and mapping them to a group of appropriate responses. The tag on each python chat bot dictionary in the file indicates the group that each message belongs too. With this data we will train a neural network to take a sentence of words and classify it as one of the tags in our file. Then we can simply take a response from those groups and display that to the user.

Can I make a WhatsApp bot in Python?

System Requirements: A Twilio account and a smartphone with an active phone number and WhatsApp installed. Must have Python 3.9 or newer installed in the system. Flask: We will be using a flask to create a web application that responds to incoming WhatsApp messages with it.

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. As you can see in the scheme below, besides the x input information, there is a pointer that connects hidden h layers, thus transmitting information from layer to layer. A chatbot is a computer program that holds an automated conversation with a human via text or speech. In other words, a chatbot simulates a human-like conversation in order to perform a specific task for an end user.

The final version of the bot

So we can have some simple logic on the frontend to redirect the user to generate a new token if an error response is generated while trying to start a chat. The messages sent and received within this chat session are stored with a Message class which creates a chat id on the fly using uuid4. The only data we need to provide when initializing this Message class is the message text. To send messages between the client and server in real-time, we need to open a socket connection. This is because an HTTP connection will not be sufficient to ensure real-time bi-directional communication between the client and the server.

Now let’s discover another way of creating chatbots, this time using the ChatterBot library. In this article, we decided to focus on creating smart bots with Python, as this language is quite popular for building AI solutions. We’ll make sure to cover other programming languages in our future posts. There are many use cases where chatbots can be applied, from customer support to sales to health assistance and beyond. Over the years, we’ve worked on many cloud, data management, and cybersecurity projects, building extensive expertise in fast and secure web application development.

Running Chatbot

We will follow a step-by-step approach and break down the procedure of creating a Python chat. # By epochs, we mean the number of times you repeat a training set. # Whilst training your Nural Network, you have the option of making the output verbose or simple.

Recall that we are sending text data over WebSockets, but our chat data needs to hold more information than just the text. We need to timestamp when the chat was sent, create an ID for each message, and collect data about the chat session, then store this data in a JSON format. Our application currently does not store any state, and there is no way to identify users or store and retrieve chat data. We are also returning a hard-coded response to the client during chat sessions.
