With the large diversity of platforms and devices used by students, web applications increasingly suggest themselves as the solution of choice. Developing adequate educational programming environments in the browser, however, remains a challenge and often involves trade-offs between desired functionalities and navigating the limitations of web applications, in particular the blocking single-threaded execution model. We introduce a fully browser-based Python programming environment that explores the possibilities and demonstrates that a web application can indeed support a rich and mature set of features, ranging from Turtle graphics over educational robotics to data processing.
