On one hand, we have created more elegant languages, and have made things faster, bigger, and more scalable on the other hand, the surrounding technologies enabling those advancements are mirrored in the complexity of their underlying infrastructures. Searching for the perfect platform to build on top of was hard. We wanted to start from the best options the ecosystem provides today. In pursuing this, we did not want to create an entirely new technology stack. We wanted to provide a reliable and accessible framework for creating and shipping applications to any hardware and software platform, while still having fun. Visual application development: Use readily available curated UI components, such as buttons, containers, text boxes, and moreįlexible framework: A flexible framework that can be leveraged to create and share new pluggable and extensible components directly in PythonĪll that to say… PyScript is just HTML, only a bit (okay, maybe a lot) more powerful, thanks to the rich and accessible ecosystem of Python libraries. Python with JavaScript: Bi-directional communication between Python and Javascript objects and namespacesĮnvironment management: Allow users to define what packages and files to include for the page code to run Python ecosystem: Run many popular packages of Python and the scientific stack (such as numpy, pandas, scikit-learn, and more) Python in the browser: Enable drop-in content, external file hosting (made possible by the Pyodide project, thank you!), and application hosting without the reliance on server-side configuration What is PyScript? Well, here are some of the core components: PyScript aims to give users a first-class programming language that has consistent styling rules, is more expressive, and is easier to learn. PyScript is a framework that allows users to create rich Python applications in the browser using a mix of Python with standard HTML. We have high hopes that this will help Python take a serious step towards making programming and data science more accessible to everyone. Today, at P圜on US 2022, I'm happy to unveil a new project that we’ve been working on here at Anaconda. I’ve embedded the REPL below.Supporting open source and creating tools that enable people to do more with less are why I joined Anaconda almost eight years ago. It does support the input() function though! The REPL It doesn’t support the underscore to get the previous result. For example, you need to enter your code and hit shift+enter or the play button to run it. Note that this resembles a regular Python REPL, but it’s not at all the same as the real Python REPL. However, I’ve found it works in Firefox and anything based on Chrome, like Chrome itself, Chromium, and Microsoft Edge. PyScript is new and experimental and was only tested in recent browsers so far. The following REPL runs entirely in your browser, thanks to the awesome PyScript project. PyScript does, by means of a simple JavaScript popup box asking for your input. The Pyodide REPL doesn’t support the input() function, for example. All you need to do, is include some JavaScript and you’re ready to use the py-script tags to include Python code in your HTML page.Īnother thing I noticed, is that PyScript is trying hard to make Python interoperate with the browser. So why is PyScript such a big deal? It’s mostly because it makes using Python in the browser more accessible. In the following screenshot, you can see the actual Python REPL running in my browser: Pyodide REPL, running in my browser What does PyScript add to Pyodide? This project did not just port CPython to web assembly, but also made the effort to compile well-known packages like Pandas and Numpy so they can be run right from the browser. Pyodide is a port of CPython to WebAssembly. PyScript runs in your browser, which is pretty amazing! Under the hood, PyScript uses a project called Pyodide. It's much appreciated and allows me to keep working on this site! I use ads to keep writing these free articles, I hope you understand!
