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. It is expected that in a few years chatbots will power 85% of all customer service interactions. This open source framework works best for building contextual chatbots that can add a more human feeling to the interactions. And, the system supports synonyms and hyponyms, so you don’t have to train the bots for every possible variation of the word. After deploying the virtual assistants, they interactively learn as they communicate with users.

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. Since these bots can learn from experiences and behavior, they can respond to a large variety of queries and commands. A great next step for your chatbot to become better at handling inputs is to include more and better training data. If you do that, and utilize all the features for customization that ChatterBot offers, then you can create a chatbot that responds a little more on point than 🪴 Chatpot here. Congratulations, you’ve built a Python chatbot using the ChatterBot library!

Why Python is best for AI ML?

Python is the major code language for AI and ML. It surpasses Java in popularity and has many advantages, such as a great library ecosystem, Good visualization options, A low entry barrier, Community support, Flexibility, Readability, and Platform independence.

An average salary of a chatbot developer ranges between $57,000 and $205,000 per year. You already thought about using a bot framework to make the process more efficient. It would be quicker and there’s a lot of people who can help you out in case of any issues.

However, if you use a framework to build your chatbots, you can do it with minimal coding knowledge. And most of the open-source chatbot services are freely available and free to use. If you decide to build your own bot without using any frameworks, you need to remember that the chatbot development ecosystem is still quite new. This means that there aren’t many guidelines or best practices.

But if you want to customize any part of the process, then it gives you all the freedom to do so. You now collect the return value of the first function call in the variable message_corpus, then use it as an argument to remove_non_message_text(). You save the result of that function call to cleaned_corpus and print that value to your console on line 14. Find the file that you saved, and download it to your machine.

I am using Windows Terminal on Windows, but you can also use Command Prompt. Once here, run the below command below, and it will output the Python version. On Linux or other platforms, you may have to use python3 —version instead of python —version. Next, run the setup file and make sure to enable the checkbox for “Add Python.exe to PATH.” This is an extremely important step. After that, click on “Install Now” and follow the usual steps to install Python. Fellow developers are your greatest help, especially when you’re starting to use a bot framework.
