AI agents are not just smarter chatbots. They generate data, use tools, write and read files, and reason across tasks automatically. In this hands-on tutorial, you’ll learn how to build a fully working AI agent in Python in under 10 minutes using LangChain, LangGraph, and custom tools — with real code, not demos. You’ll create an AI agent called DataGen that can: • Generate realistic user data • Save it into JSON files • Read files back • Answer questions using tool-based reasoning All inside a real Python project you can extend, customize, and reuse. This is not theory. This is practical AI agent engineering. Whether you’re a developer, student, data professional, or AI enthusiast, this video shows exactly how modern AI agents work behind the scenes — from environment setup to tool orchestration. This is the builder’s version of AI. Not prompts. Not demos. Real code. Real agents. Link to code snippets:- https://github.com/kushagraxd/PythonAIAgent 👉 Want more like this? We’re building a complete AI Agents & Automation Playlist on the NIIT channel with hands-on projects, workflows, and production-ready patterns. What you’ll learn in this video: • What an AI agent really is (beyond chatbots) • How agents use tools, memory, and reasoning • Setting up a Python project using UV • Creating tools to generate, write, and read JSON data • Using LangChain + LangGraph to control agent behavior • Building an interactive terminal-based AI agent • Running, testing, and extending your agent • How to scale this into real automation systems Why AI Agents Matter: AI agents don’t replace people. They replace repetitive work — data generation, file handling, decision routing — so humans can focus on logic, creativity, and design. At NIIT, we turn emerging tech into job-ready skills you can apply at work. If you want to build AI, not just talk about it, you’re in the right place. 👇 Comment below: What should we build next?
