I mean yeah but no. Any higher level language that you see is usually written in a medium or lower level language. PyScript is written in JS, nothing really surprising but imagine this, PyScript runs on JS, JS runs on V8, V8 is written in C++ and lets you do stuff. This is just an additional and unnecessary step. I really hope PyScript doesn't really become a thing. Right now, it's going to be slower even more than JS. For browsers to natively support this would take years if not a decade. Would've been better if the compiler was written in Web Assembly. Not sure how big or small the bundle size would be with Web Assembly though.

This is a really cool project, but honestly the only reason I can see for using it is bringing awesome python libs like matplotlib, pandas, sympy etc. to the browser. For the rest I see no reason or need to use it, the javascript ecosystem is huge and powerful. Why would any frontend developer switch to the python apis if he or she is comfortable in the js apis? Only thing is that this makes the web more accessible for python developers and lowers the threshold to get started with frontend development for them.

For the same reasons tons of devs are using node on the backend while there isn't really any reason one would want his backend in JavaScript, they just want to only use one language for both be and fe. Well tons of people are still actually using python on the backend and switch to JS for the fe, if a framework like React with python was good enough I could see myself trying it. These days you actually write tons of logic in the front end so wanting python is natural and goes beyond the inability of some for writing js.

[@Ma1ne2]

@@heroe1486 The only difference being that JavaScript is tightly integrated and standardised in the browser. The APIs developed over years, as well as the frameworks and libraries around it. It will take Python years or decades to catch up with this. It is based on a compilation to WebAssembly which is fast and great but also these binding have to develop over time and improve to reach the level of flexibility JavaScript offers today. I am just saying there is a lot of work to do and no real upside for any current web developer to switch. As I wrote in my first comment, that is not the case for new python developers coming to the frontend, which is great. But for them it will be a long way to establish the kind of ecosystem JavaScript has today.

"The end of Javascript". For educational purposes, if you remove the V8 runtime from your browser your script will no longer work. The video is intuitive despite the title, don't do this. It has already been demonstrated many times by many contributors of Python, Chromium and Mozilla that Python is not suitable for the Web. Anyway, people are used to using JS which is undoubtedly the language of the Web and will never be replaced simply because it would break more than 3/4 of the current Web. Also, the V8 JIT compiler performs better than the Python one, I base this on my own tests as a JIT compiler developer. And it is optimized for the web to reduce the memory footprint, unlike Python which was not designed with this in mind. If you want to use Python on the Web only because you miss Tensorflow and Keras, either follow the documentation and install them locally, or wait a few months until the GPU Web API and other machine learning APIs are available on Chrome. This will be much more efficient than using a port of the Python runtime in WebAssembly. At least 10 times more.

[@G-33k]

This is very exciting, Thank you for informing us about it, now as pythonistas we must contribute and build a community about pyscript :D

[@kibe2134]

As someone who works with both JavaScript and Python, I can assure you that even though this is a nice proof of concept, no front-end developer in their right mind would ever touch something like this. The JavaScript ecosystem is just so much more mature than Python's that it's basically impossible to catch up at this point. Think about the different between NPM and PIP. One is a proper packages manager, the other doesn't even handle requirement files decently. Other example would be, say, the import systems in both languages; JavaScript's is concise, efficient and easy to understand, meanwhile, Python's is a mess. I understand that a lot of people will always try to use anything for the web but JavaScript in the same way that americans will measure with anything but the metric system, but at some point they will have to understand that it is, and will continue to be for the foreseeable future, the best language to build interfaces. Period. It's the language's purpose, and it's why people will use it everywhere. Web? JavaScript. Mobile? JavaScript with React Native or Cordova or Ionic. Desktop? JavaScript with Electron or Tauri or (who remembers?) NW.JS. I mean, if we're really being honest, the reason augmented reality is not mainstream os probably because there's no JavaScript frameworks for it. Don't get me wrong, I love Python, and as of now, it's my main source of income, but it's simply not meant to compete with JavaScript in the the things JavaScript is good at. TLDR; if I ever see a job offer from a company that has this in it's stack, I'll know to stay away from it, for they're clearly out of their minds.

[@FilipCordas]

Even if this Python in the browser is years old you can make a case for this not as a UI thing but as running backed stuff in your app. Things seam to be going the web components way that means a lot of UI frameworks will be usable for Python in the browser. Don't get me wrong Python is the worst language out there to use for anything so the issue not being a good way to do things has never been a problem for Python dev's. This should just work in Electron and Cordova and tauri... since it's just WebAssembly. And mixing JS and Python is already done in notebooks since most of the charts are just wrappers for JS plotting libraries.

Cool rant. It will take a year or two to catch up if its adopted at python like scale. Not arguing if it's better, just arguing you underestimating just how popular python is.

[@Netrole]

It is a nice idea and might be awesome for the hard core python fans. But my concern is that this sacrifices the user experience in exchange for dev experience, which is certainly the wrong way around. After all, each user has to download the python interpreter, and the code will run a lot slower than javascript, since python is not optimized by the browser. Additionally a lot of pythons performance comes from super fast packages like numpy that are written in C, however these are slowed down significantly through webassembly. Because under the hood webassembly uses the same VM code as javascript, so WebAssembly performance == JavaScript performance.

[@benjaminscherrey1124]

I think the point is that you can be a "full stack" web dev and need only code in Python. That's pretty amazing. No one is suggesting that all python apps should now run in a browser.

no not every user has to download the python interpreter what are you on about and wtf do you mean by WebAssembly performance == JavaScript performance LOL

[@Netrole]

@Marcus - Yes and no, WASM has some performance benefits, but peak performance is the same as peak performance for JS. WASM is more consistent and it is easier to maintain peak performance, while javascript can have performance bailouts where it drops back to being interpreted which is a significant slowdown. WASM also has the performance benefit of compiler optimizations. Overall what i wanted to say though is, that WASM is significantly slower than the C implementations used in regular Python. And that a well written javascript implementation is just as fast. Actually a well written javascript implementation might be faster because it has access to the javascript "standard library" like Array.sort() which execute highly optimized assembler code in most browsers

[@theaninova]

I mean... I get it, for use cases where you really need specific Python packages... But not without some SERIOUS performance issues. This comes from just the Hello World Example 1. 290 kb of CSS and 300 kb of JS dependencies 2. 7 *MB* for the Python interpreter 3. 1.2 *MB* for dependencies Just for a Hello World example. Unless this gets built into browsers natively, you're absolutely gonna KILL your site's performance. Almost 9MB you can't get rid of is an INSANE amount of data, and on top you're running a Python interpreter in webassembly. Use sparingly when you have no alternatives left.

Just importing a bunch of Python files in the index.html file will get really hard to maintain and code-split which led to JS web frameworks and libraries being adopted and now widely used. So definitively JS is not being replaced by PScript and JS web development positions will not magically be replaced with Python. I know you understand it, it’s just for the annoying people always thinking there is some war of dominance for which language to rule them all. Best thing as usual to learn both JS and Python, and decide which one is best suited for your case.

Its really really new and in early stage but its still exiting.

@@puffin_000 why is it a problem if someone writes something in python instead of js? Pyscript CANT do more than js because it is a mix of js/wasm running in the browsers sandbox.

[@puffin_000]

@@michaelbitzer7295 Because problem is compiler, the python code is translate into javascript code and if somebody don't know how to write js they can't detect vulnerability.

Thanks for sharing the basic ideas of Pyscript. Can you please also share how did you load Mario game environment using Pyscript?

[@bufkinsmith7650]

Why wouldn’t I just write my code in Python and then compile to WASM if I wanted this? Isn’t there going to be a significant difference in performance if it’s just straight Python?

[@rattlehead999]

You can also run C# in the browser thanks to Blazor and I'm pretty sure Java had an alternative as well.

[@barodrinksbeer7484]

I took a look at it, its super interesting. However, right now it seems to much of a mixture of things, I still was using JS when I tried integrating a simple target practice game. I can see useful reasons to have Python integrated into HTML. However, I don't see this doing better then JavaScript.

[@hououinkyouma5372]

Naturally. This is a prime example of "doing it because you can". Besides, downloading a huge CPython interpretor on every page refresh is just not following any of the web dev practices. I suppose this will give AI/ML guys some new things to tinker with, but it'll definitely not be used for web dev. Not yet anyway.

[@rondamon4408]

Numpy is written in C. Do we lose performance when using on the browser?

[@deaddoctor]

i think it would be slower because it would use webassembly

[@egelbets]

Is it also possible to get data in a tag when rendering the HTML template? For example with Flask I can pass on variables into the render_template() function that I then can access in the template using Jinja. Can I also do this with pyscript?

[@nickfla1]

code inside a pyscript is interpreted once the page has been loaded, so yes, as long as it's server side rendered

[@AxiomTutor]

This looks incredible!

Thx great info, just learning python and solidity / blockchain

[@davies8183]

The last time I did a python project, I had to implement most of my logic in C to make the performance bearable to users. I think python should just stick to data science. Wasm is here, I get it but with languages like GO, Rust, and C# on the web, it doesn't stand a chance for any serious web apps.

[@davies8183]

@Marcus - Don't be fooled by the hype. Most companies are using C++, C#, Go and Rust to run most of their core apps. We don't pick tools because they're easy. We pick the tools that get the job done and offer the best experience to the user.

Very odd that those not able to learn how to use python stand alone can just use the functions and tools now yet apparently could not before. How was it appearing online before then? How did the code get results in browsers before? Any answers that might help me understand are great as I can see some simple code in Python but not otherwise how it operated except inside it's own environment.

​@@codingcrashkurse6429 Had already looked at the code, pyodide is the actual engine behind pyscript. It's a wasm porting of CPython, performance might be quite ok but I can't see any benefits other then using _some_ of the Python ecosystem directly on the frontend. My biggest concern is that people start building applications with these libraries and create an even more bloated web

[@nickfla1]

Also we should really give the credits to pyodide's team! pyscript it's really just a component-based wrapper, useful but not the "ground breaking" technology here
