How to Make a Chatbot in Python

Next, we need to update the main function to add new messages to the cache, read the previous 4 messages from the cache, and then make an API call to the model using the query method. It’ll have a payload consisting of a composite string of the last 4 messages. Update to include the create_rejson_connection method. Also, update the .env file with the authentication data, and ensure rejson is installed.

The test route will return a simple JSON response that tells us the API is online. Next, install a couple of libraries in your Python environment. In the next section, we will build our chat web server using FastAPI and Python. I’ve carefully divided the project into sections to ensure that you can easily select the phase that is important to you in case you do not wish to code the full application. We now just have to take the input from the user and call the previously defined functions.

All these tools may seem intimidating at first, but believe me, the steps are easy and can be deployed by anyone. Since there is no text pre-processing and classification done here, we have to be very careful with the corpus [pairs, refelctions] to make it very generic yet differentiable. This is necessary to avoid misinterpretations and wrong answers displayed by the chatbot. Such simple chat utilities could be used on applications where the inputs have to be rule-based and follow a strict pattern. For example, this can be an effective, lightweight automation bot that an inventory manager can use to query every time he/she wants to track the location of a product/s. In the above snippet of code, we have imported the ChatterBotCorpusTrainer class from the chatterbot.trainers module.

Your chatbot has increased its range of responses based on the training data that you fed to it. As you might notice when you interact with your chatbot, the responses don’t always make a lot of sense. For example, you may notice that the first line of the provided chat export isn’t part of the conversation. Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender. It’s rare that input data comes exactly in the form that you need it, so you’ll clean the chat export data to get it into a useful input format.

What is ChatterBot Library?

The code samples we’ve shared are versatile and can serve as building blocks for similar chatbot projects. As the topic suggests we are here to help you have a conversation with your AI today. To have a conversation with your AI, you need a few pre-trained tools which can help you build an AI chatbot system. In this article, we will guide you to combine speech recognition processes with an artificial intelligence algorithm. In this article, we will create an AI chatbot using Natural Language Processing (NLP) in Python. First, we’ll explain NLP, which helps computers understand human language.

Chatbot or chatterbot is becoming very popular nowadays due to their Instantaneous response, 24-hour service, and ease of communication. Let’s go through the process of implementing a chatbot in Python. A corpus is a collection of authentic text or audio that has been organised into datasets.


A fork might also come with additional installation instructions. To extract the city name, you get all the named entities in the user’s statement and check which of them is a geopolitical entity (country, state, city). If it is, then you save the name of the entity (its text) in a variable called city. Next, you’ll create a function to get the current weather in a city from the OpenWeather API.

And that is how you build your own AI chatbot with the ChatGPT API. Now, you can ask any question you want and get answers in a jiffy. In addition to ChatGPT alternatives, you can use your own chatbot instead of the official website. Gradio allows you to quickly develop a friendly web interface so that you can demo your AI chatbot. It also lets you easily share the chatbot on the internet through a shareable link. Now, it’s time to install the OpenAI library, which will allow us to interact with ChatGPT through their API.

You’ll also create a working command-line chatbot that can reply to you—but it won’t have very interesting replies for you yet. You’ll get the basic chatbot up and running right away in step one, but the most interesting part is the learning phase, when you get to train your chatbot. The quality and preparation of your training data will make a big difference in your chatbot’s performance. You have created a chatbot that is intelligent enough to respond to a user’s statement—even when the user phrases their statement in different ways. The chatbot uses the OpenWeather API to get the current weather in a city specified by the user.

Once our keywords list is complete, we need to build up a dictionary that matches our keywords to intents. We also need to reformat the keywords in a special syntax that makes them visible to Regular Expression’s search function. The following are the steps for building an AI-powered chatbot.

By leveraging the API’s capabilities, you can enhance your dialog

systems and platforms with intelligent conversational potential. Pip is the package allowing you to easily install,

upgrade, and manage its libraries and dependencies. By ensuring it is up to [newline]date, you’ll have the latest features and bug fixes, which will be helpful

when installing libraries for your AI chatbot. Click the “Create new secret key” button and follow the [newline]required steps.

You can build a chatbot that can provide answers to your customers’ queries, take payments, recommend products, or even direct incoming calls. The chatbot picked the greeting from the first user input (‘Hi’) and responded according to the matched intent. The same happened when it located the word (‘time’) in the second user input. The third user input (‘How can I open a bank account’) didn’t have any keywords that present in Bankbot’s database and so it went to its fallback intent. Natural Language Toolkit is a Python library that makes it easy to process human language data.

If those two statements execute without any errors, then you have spaCy installed. In the AIML we can set predicates using the set response in template. We don’t know if the bot was joking about the snowball store, but the conversation is quite amusing compared to the previous generations.
