Lesson 0: Python Basics — AgentCraft

Variables, strings, lists, dicts, if/for, functions, and methods — the Python syntax every AgentCraft lesson uses. No LLM required; runs in your browser.

Chapter 0: Python in five minutes The interactive lessons use Python — the language you see in the code blocks. You do not install anything: a copy of Python runs inside your browser. How to read Python • Indentation (spaces at the start of a line) groups lines into blocks. After a line ending with :, the next lines must be indented until the block ends. • # starts a comment: Python ignores the rest of that line. • Quotes wrap text: "like this" or 'like this'. This chapter introduces the pieces that appear again and again in the agent code: names for values, lists, dictionaries, decisions, loops, and functions.

Framework comparison: Later lessons add `async` and HTTP calls. Same Python syntax — just more moving parts.
