You can check it out at http://www.brython.info/ . You can use run LLVM in JavaScript using ECMAScripten. This means you can compile c-python from C to JavaScript and just run JS in the browser. The link to the ECMAScripten wiki provides more details on how to do that.
Jan 10, 2024 · PyScript lets you run Python scripts right in the browser, side by side with JavaScript, with two-way interaction between your code and the web page.

Let me tell you about me: I used to be a back-end Python developer. I was happy. And then I got a job writing front-endJavaScript code too. This was…less happy. I was using two languages with very different ways of thinking. Both my brain and my app logic were getting scrambled between the two, and I was constantly missing the features and usabilit...
These six technologies that are representative examples of what’s out there. They’re all relatively mature, and they cover a lot of the design space. I’ve put them on two axes: Our first big design choice is on the Y-axis: How is the Python being run by the browser?You have two options: either translate the Python code to Javascript and then run th...
The first we’ll talk about is Transcrypt. This is a compiler that translates Python into JavaScript ahead-of-time. I’ll show you a quick example: I have two files: hello.html and hello.py. hello.htmlis an incredibly simple HTML file: it has an input box and a button. When I type my name into the input box, I’m going to get an alert. The dynamic beh...
If I want a Python
Skulptwas originally written for education, to provide an interactive Python environment inthe browser. If you’re just getting someone started with Python, you really don’t want their first experience to be downloading and installing it! They might ruin their system Python in theprocess, you’ve got as many different environments as you have student...
Writing a Python interpreter and compiler in JavaScript sounds like a lot of work, but PyPy.js found a way around that.Instead of rewriting Python in JavaScript, which would take years, they recompiled PyPy toJavaScript using emscripten. That gives you a JavaScript version of PyPy. They didn’t stop there – they alsobuilt a just-in-time Python-to-Ja...
It’s called Batavia and it’s from Beeware.They’re an open-source project who make lots of really cool tools that make Python even more portable that it already is. Batavia is their Python-in-the-browser solution and they have literally hand-written a Python interpreter in JavaScript.They haven’t written the compiler – it just interprets precompiled...
Last but not least, I want to talk about Pyodide. It’s a full environment, a bit like a Jupyter Notebook, but it runs entirely in your browser. Youcan have data science pipelines fully in the client, so there’s no roundtrips and everything’s a lot faster. It’s run by Mozilla, and it works by compiling the standard CPython interpreter to WebAssembly...
So this concludes our tour. Here’s a summary table of all the technologies I talked about(also available in the accompanying Python Tipsblog post):
I want to make a broader point. As I said at the beginning: I think we need to be asking that question about the whole web stack. The web stack started out as the thing on the left of this diagram, where you’re using SQL for your data access,you have to convert things to JSON, you have to write HTML templates, you have to use the Document Object Mo...
Mar 15, 2023 · The main advantage of Pyodide is that it allows you to run Python code directly in the browser, without needing to install anything on the server or the client side. This means that you can write web applications entirely in Python, without needing to learn another language or use a separate backend.
May 22, 2019 · At one extreme, you run a command-line script to compile Python yourself. At the other extreme, the compilation gets done in the user’s browser as they write Python code. The y-axis answers the question: what does Python get compiled to? Three systems make a direct conversion between the Python you write and some equivalent JavaScript.
Nov 30, 2021 · Ethan Smith, a Berkeley-based software developer, recently revealed a project that allows CPython, the default implementation of the Python programming language, to run within web browsers via WebAssembly, or WASM. WASM is a binary format that provides near-native performance within web browsers.

You need to use a browser that supports cross-origin isolation. The extension has been tested with the Microsoft Edge and Google Chrome browsers. You need to use the insider version of VS Code for the Web (for example https://insiders.vscode.dev/)
