announcement

Pandas Tutor is a data science education tool that visualizes how pandas code transforms dataframes. In this guest post we discuss how we ported it to run 100% in-browser with Pyodide.

Pyodide 0.20 is a major release focused on improving our system for building and packaging Python modules. We upgraded to Python 3.10. This comes with a speed boost of around 15% in Firefox and 22% in Chrome. We updated almost every package to the most recent release, and moved closer to using upstream Emscripten. Pyodide 0.20 also includes many small bug fixes and usability improvements. For the complete list of changes see the changelog....

From web servers to end-to-end Data pipelines, Python has become a ubiquitous tool for building all sorts of programs and software. With powerful built-in libraries and an incredible number of third-party libraries, the Python ecosystem makes it easy to quickly get your project started. In fact, building user interfaces (UIs) is not an exception: PyQT allows you to create cross-platform desktop applications, whereas libraries like Dash allows you to create full-fledged web applications (including the UI) within a single Python script....

Pyodide 0.19 is a major release focused on improving the build system, updating scientific computing packages, and improving the workflow for loading Python code. Here are a few highlights. For the complete list of changes see the changelog. Removal of function pointer cast emulation Some Python C extensions use function pointer casting, which is an unspecified behavior according to the C specification. However, all common native C compilers generate code that works fine....

We would like to announce that Pyodide is now a member of the Open Source Collective (OSC), which will act as the project’s fiscal host. The Pyodide project compiles Python and the scientific stack to WebAssembly using Emscripten. Pyodide was created in 2018 by Michael Droettboom at Mozilla as part of the Iodide project. Later in 2021 Pyodide became an independent open-source project, and the current announcement completes this transition....
