Time to get hands on. Install a real AI coding editor, sign in, and write your first line together. No credit card required to start.
You have two clean ways to get started in 2026: Cursor (a full AI-first IDE) or VS Code with the GitHub Copilot extension. Both have free tiers that are good enough for every lesson in this track. Pick one and stop agonizing over the choice.
# Type this comment on line 1: # Function that returns the first N Fibonacci numbers as a list. # Press Enter. Wait two seconds. Gray text should appear. # Accept with Tab. You should see something like: def fibonacci(n): sequence = [0, 1] while len(sequence) < n: sequence.append(sequence[-1] + sequence[-2]) return sequence[:n] print(fibonacci(10))If you see gray autocomplete text appear, your setup works. Save the file, open a terminal, and run `python fib.py`.The best editor is the one you actually open every day.
— Every senior dev, eventually
The big idea: setup is not the lesson, but it is the gate. Install one of these two, verify ghost text works, and you are ready for everything that follows.
