Python

友好、强大、无处不在。

Python is the friendly, readable language behind data science, AI, automation and countless web services. This track starts from zero but moves fast: install Python 3.14, master its types and data structures, write functions and classes, handle errors and files, then build real tools with HTTP, a command-line interface, automated tests and async code.

Every lesson is short, practical and checked with quizzes, so you learn by doing.
