Cursor is an AI-powered integrated development environment (IDE) based on the Visual Studio Code codebase. It comes with a multi-agent interface and the Composer model for fast, agentic coding while keeping a familiar editor workflow with project-aware chat, code completion, and inline edits. In this course, you will: Understand why Cursor might work for you Learn how to use different modes & models See how to run multiple agents at a time Resolve a tiny merge conflict Run a project […]

As we welcome 2026, it’s time to look back on an exciting year for Python. Python 3.14 arrived with a wave of developer-focused improvements, from lazy annotations that finally resolve long-standing type hinting quirks to clever new t-strings that give you more control over string interpolation. Meanwhile, 2025 was the year AI tools truly became part of everyday Python development. From agentic coding with LangGraph to connecting LLMs to your data via MCP servers, Python solidified its position as the […]

Interactive Quiz ⋅ 8 QuestionsBy Leodanis Pozo Ramos Share In this quiz, you’ll test your understanding of the LlamaIndex in Python: A RAG Guide With Examples tutorial. By working through this quiz, you’ll revisit how to create and persist an index to disk, review how to reload it, and see why persistence improves performance, lowers costs, saves time, and keeps results consistent. The quiz contains 8 questions and there is no time limit. You’ll get 1 point for each correct […]

Discover how to use LlamaIndex with practical examples. This framework helps you build retrieval-augmented generation (RAG) apps using Python. LlamaIndex lets you load your data and documents, create and persist searchable indexes, and query an LLM using your data as context. In this tutorial, you’ll learn the basics of installing the package, setting AI providers, spinning up a query engine, and running synchronous or asynchronous queries against remote or local models. By the end of this tutorial, you’ll understand that: […]

Interactive Quiz ⋅ 10 QuestionsBy Joseph Peart Share In this quiz, you’ll test your understanding of Recursion in Python. By working through this quiz, you’ll revisit what recursion is, how base and recursive cases work, when recursion is a good fit for a problem, and when an iterative approach fits. The quiz contains 10 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end of the quiz, you’ll receive a total score. […]

You may often want to make your Python programs more interactive by responding dynamically to input from the user. Learning how to read user input from the keyboard unlocks exciting possibilities and can make your code far more useful. The ability to gather input from the keyboard with Python allows you to build programs that can respond uniquely based on the preferences, decisions, or data provided by different users. By fetching input and assigning it to variables, your code can […]

Interactive Quiz ⋅ 6 QuestionsBy Leodanis Pozo Ramos Share In this quiz, you’ll test your understanding of the SOLID Design Principles: Improve Object-Oriented Code in Python tutorial. You will reason about behavior contracts, attribute invariants, and choosing composition or separate types over inheritance. For a refresher, you can watch the Design and Guidance: Object-Oriented Programming in Python course. The quiz contains 6 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end […]

Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Design and Guidance: Object-Oriented Programming in Python A great approach to writing high-quality object-oriented Python code is to consistently apply the SOLID design principles. SOLID is a set of five object-oriented design principles that can help you write maintainable, flexible, and scalable code based on well-designed, cleanly structured classes. These principles are foundational best […]

When you’re learning Python, the sheer volume of topics to explore can feel overwhelming because there’s so much you could focus on. Should you dive into web frameworks before exploring data science? Is test-driven development something you need right away? And which skills actually matter to employers in the age of AI-assisted software development? Python itself is relatively beginner-friendly, but its versatility makes it easy to wander without direction. Without a clear plan, you can spend months studying topics that […]

When you write asynchronous code in Python, you’ll likely need to create asynchronous iterators and iterables at some point. Asynchronous iterators are what Python uses to control async for loops, while asynchronous iterables are objects that you can iterate over using async for loops. Both tools allow you to iterate over awaitable objects without blocking your code. This way, you can perform different tasks asynchronously. In this video course, you’ll: Learn what async iterators and iterables are in Python Create […]
