A player of Genshin Impact, the popular role-playing game, has built an interactive course on the Python programming language inside it. He used the in-game constructor Astral Limit, which allows players to create their own levels and mini-games.
The course is structured like a real textbook. The first lesson is called "Hello, Python." The player is presented with an exercise, a code editor, buttons for running and resetting the program, and a hint containing a ready-made solution. The code has to be typed on a virtual keyboard, and the result is displayed on screen immediately. To find the course, one must enter its number in the game: 81740808160. Apparently, it is so far available only on the Asian server.
The Astral Limit mode appeared in Genshin Impact in October 2025. It resembles the constructors in Roblox and Fortnite Creative. Levels can only be created on a computer, and to play them a special character is used rather than the heroes from the main game.
