New tutorial teaches beginners to build a simple AI chatbot using Python

A new tutorial shows how to create a simple AI chatbot using Python and the Natural Language Toolkit (NLTK). This chatbot operates in a terminal and can respond to greetings, questions, and farewells. The tutorial guides users through installing NLTK and building the chatbot's basic structure. It includes functions for tokenizing user input, identifying question types, and generating responses based on sentiment analysis. While the chatbot can handle basic interactions, it lacks a comprehensive knowledge base. Users are encouraged to explore further improvements, such as enhancing the chatbot's knowledge and user interface.
