If your focus is on a language, JavaScript versus Python, then you are missing to objective of PyScript. AI, ML and Data Science are Python frameworks. Now that you can run those frameworks in the browser is very significant. PyScript is not targeting the web developer. PyScript is targeting the Data Science, AI and ML developer who wants to move CPU cycles from the backend to the frontend. That is a major feature and has global implications on how next generation systems will be designed.

[@jorge1869]

Agree👌

[@whilechannel]

Tensorflow JS….

[@jorge1869]

Beautiful, better explained impossible, totally agree with you.

[@mage1over137]

While I agree that this is important for all the reasons you said, it's more general than that. The reason why python is the language of big data, is that it's easier to write to awesome tooling. The fact JavaScript is the language in the browser is an historical accident, and an unfortunate one at that. But now that pyscript is an option I think we are going to see some real magic happen. I'm working on setting up a Prefect agent in the browser, so you can have reactive pyscript elements in the UI. Once pyscript becomes more mature, I think we will see python as the language of the entire stack, and the reason is simply economics. It's cheaper and easier to maintain having the whole project in one language opposed to having both python in and JS devs.

[@mage1over137]

​@@whilechannelthat's one library, vs all of the tooling you get with python.

[@spotted756]

@Stefan, it actually depends. There's a bunch of data scientists working big corporations that could develop their MVPs/POCs and/or internal tools entirely in Python.

[@losiu998]

Yea, there already frameworks like Dash/Streamlit that empowers data scientists to create dashboards. I think Pyscript could help them to create more advanced dashboards but I don't see any other usecase.

[@bjeribs]

Great talk. It’s interesting to see where it goes my guess is maybe data science in the browser

[@fredericoamigo]

Good points and a lot of wisdom as usual! However, when it comes to pyscript, I must say I think it is really exiting. There are lots of people learning python right now, meaning there’ll be a big community of pyscript in the future. It probably won’t replace JavaScript, but I wouldn’t be surprised if pyscript becomes a major player in the future, maybe for making dashboards etc. I’ve checked it out a bit, and it works really well! I especially like that it works great with numpy and matplotlib. Anyway, my point is, I don’t disagree with you, but i don’t think people should underestimate pyscript either. It’s a great tool that shows a great potential:-)

[@paulholsters7932]

Like so many tools show great potential and are very popular. But niche and not widely used. But indeed it might. But for a newbie I would recommend learning frontend development with JS instead of pycharm no matter how unbelievably fast and great and better it is.

[@ukaszzbrozek6470]

Python in a browser would be use for very specific use cases like AI and machine learning. JS isn't very good with complex calculations and is really painful to rewrite and update packages for It that already exist in Python. Basically the use case is that company want to use computing power of user by moving solution from server to website without rewriting it. That is brilliant and would stay with us.

[@danielihenacho]

Except Pyscript would be used for niche applications, probably somewhere like ML and Data Science, I guess. Just my thoughts on it.

[@virtualvessel0]

Absolutely, I don't see it as a replacer, but...simply pulling into a browser a Python runtime in one line. Far easier than deploying/configuring and calling a container to run your code.

[@abcq1]

Hi, Stef. Thanks for the talk, agree with you. But there's another thing that came out recently and aims to replace Node. I'm talking about new JS runtime called Bun . Are you familiar with it and would you like to share your thought on that. Is it something worth to consider nowadays? Unlike PyScript, authors of Bun claim that it does more than Node and does it enormously faster.

[@orazgulcayew2189]

if I didn't see your comment I would say this

[@ukaszzbrozek6470]

What I understund Bun is going compatible with npm packeges. It should be possible to move all code wroten for node.js to Bun. Bun is many times fastes so it is going to replace node and deno.

[@paulholsters7932]

If it’s going to replace it just being faster is not enough and even then it will take at least a decade. The tooling around a techstack like a UI component library like Prime is what’s 100 times more important than speed because it makes you create beautiful stuff much faster. The ecosystem around bun is ZERO. Number of jobs is ZERO. Can’t you add up one and one?

Pyscript is more than anything else an example of what is possible with wasm. For example, an html based reporting engine written with Pyscript using pandas and OOP in python would be great.

[@paulholsters7932]

Well it seems to be a trend to use your favorite backend language also in the frontend: node JavaScript - blazor c# - rust WASM and now python pycharm. Seems like a natural development. The most important thing is the ecosystem around a techstack . Things like a ui component library. That will boom your write speed. The tech is secondary. Completely agree with what’s said: it’s all about writespeed. Unless you have an app that is used by millions of people. But that is only 1% of apps.

[@NewLondonMarshall]

*pyscript. PyCharm is an IDE :)

[@PerpetualPreponderer]

With all these high level simpler syntax languages prioritising write speed over run time, I've been wondering for some time, and nowadays quite perplexed...how do these high level languages actually get the machine to do stuff? Like does it have to be compiled to a lower level language like C & then recompiled to something like assembly in order to actually instruct the hardware? Or are we somehow past that now???

[@HmongCrypto]

I love python. I use it for everything. But recently, I been having problems with it when it comes to web development specifically web3. Their are definitely more libraries to work with javascript when it comes to web3. Python is great for data science, machine learning.....etc I see pyscript as something that will bridge javascript & python. I don't see pyscript as a standalone. More so....an extension or add-on

[@sevdalink6676]

"Speed of write time is far more important than runtime" - I wouldn't say that this is always the case (watched only 5mins of that video so I apologize if this has been addressed later on in the video). Yes, A LOT of the time it is very much true - that's why scripting languages like JS or Python are so popular. But there are also performance-critical applications that require good runtime performance. But those are usually not in the browser and not for consumer-facing applications. Just wanted to say that your statement is very often true, but not always!

[@StefanMischook]

I agree, and if I had to put a number to it, I’d say 95% + of the time you don’t have to worry about runtime speed.

[@manm5302]

Agree with you on run time speed being key in some industries. I remember Elon Musk told Lex Friedman that Tesla AI is using a lot of C and C++. They need to squeeze every microsecond out of the processor.

For anyone looking for a space to innovate - here's an established 'technology' that should be erased from the face of the Earth and buried 6 feet under: CSS. 1. It doesn't support very common operations (eg. no justify-vertically) 2. Theoretically supported operations do not work on their own, because they require certain configuration of parent-child elements, so 3. Instead of having to set a single property you need to set a whole set of them (eg flexbox), 4. Working with CSS consists of finding workarounds for its inherent deficiencies.

Python is quite old, it could have been done before and wasn’t. With the popularity of React, Anguilar, NodeJS, Vue, Svelte, etc etc. The fact that it’s built into browsers. The fact that JavaScript is also generally faster and backends support more traffic.

Pyscript doesn't have to out perform JS; it just has to be good enough that the end user can't tell the difference, and easier to use then JS. And here's why, while JS is very established as the browser language, it's still a mess of language. Python3.10 or above is a much more modern language with much better tooling than JS can ever hope to be. But crux of it, it will be cheaper to have your backend language and front end language the same, and I don't see NodeJS replacing python on the backend.
