编程基础
从第一行代码开始，像程序员一样思考。
Never written a line of code? Start here. This track teaches the ideas behind every programming language: values and variables, decisions, loops, functions, lists and dictionaries, and how to break a problem into steps and fix your own bugs.
You write real Python 3.14 from the very first lesson and see how the same ideas look in JavaScript. Every lesson is short and packed with quizzes, so you learn by doing.
