派森咖啡
可落地的编程课操作系统 / A deployable coding-class OS
项目介绍 / Project Overview
派森咖啡是一套可复制的 Python 入门课堂系统：场景化关卡、本机浏览器写代码（Pyodide）、单机 / 严格全屏 / 教师机服务端三种开法，并已打学生端安装包。换一间机房、换一批学生，流程不变。公开介绍只讲课堂体验与系统能力，不发布任何教材扫描件。 / Python Café is a replicable intro-Python class system: staged café lessons, in-browser coding (Pyodide), solo / locked-fullscreen / teacher-server modes, plus a student installer. New lab, new cohort—same flow. The public page sells the class system, never a scanned textbook.
问题 / THE PROBLEM
解决什么问题 / What problem it solves
Python 入门常卡在环境安装、教材翻页和「写了跑不起来」。机房换一批学生就要重配一遍，课很难像产品一样交付。 / Intro Python stalls on installs, page-flipping and code that will not run. Every new lab cohort means re-setup—the class does not ship like a product.
理念 / RATIONALE
编程课应该是可安装的操作系统 / A coding class should be an installable OS
理念来源 / Source · 本产品提出 · Deployable Class OS（即写即跑 + 可复制开课）
把入门课收成场景关卡 + 浏览器运行时 + 三种开课模式。学生写了就能跑；老师复制到另一间机房还能开。不靠公开扫描教材。 / Pack intro class as staged scenes + in-browser runtime + three launch modes. Students write and run; teachers copy to another lab and teach. No scanned textbooks on the public site.
开课可复制 / Launch is copyable
单机 / 全屏 / 教师机服务端，换机房流程不变。 / Solo / fullscreen / teacher-server—same flow in a new lab.
场景化动机 / Situated motivation
咖啡馆任务让练习有情境，不是干题单。 / Café tasks give practice a situation, not a dry list.
操作 / HOW IT RUNS
怎么实际操作 / How it works
机房安装学生端或打开本地页；选开课模式；学生按关卡写代码提交。 / Install the student build or open the local page; pick a launch mode; students code through stages.
- 01
选开法 / Pick a launch
单机演示、严格全屏考试感、或教师机服务端统管。 / Solo demo, locked fullscreen, or teacher-server control.
- 02
做关卡 / Run stages
咖啡馆场景里完成练习，浏览器内运行。 / Finish café stages with in-browser runs.
- 03
换机房 / Move labs
带着安装包走；不重写课。 / Take the installer; do not rewrite the course.
进度 / WHERE IT IS NOW
现在到哪一步 / Where it is now
机房可交付：关卡、三种开法与学生端打包已齐。公开站只介绍系统，不放教材原文。 / Lab-ready: stages, three modes and student package. Public site describes the system, not textbook text.
我的工作 / My Contribution
我设计场景关卡、开课模式与学生端打包，让编程课能像产品一样交付。 / I designed the café stages, launch modes and student package so a coding class ships like a product.
换机房即开课 / New lab, same launch
安装包 + 三种开法，复制到另一间机房就能上。 / Installer plus three modes: copy to another lab and teach.
写了就能跑 / Write it, run it
浏览器里完成练习，反馈当场出现。 / Practice in the browser; feedback is instant.
系统可扩展 / Built to expand
关卡与开课模式是产品骨架，后面还能加章、加模式。 / Stages and launch modes are the product spine—more chapters and modes can plug in.
