I love it how the web development industry keeps on inventing new ways to render the exact same thing; just to keep us busy...

Finally JS is becoming quite fast but to balance that humanity decided to run python in the browser. 😂

As much as this is unique and welcome, I can't imagine Pyscript becoming big among the other 100 web frameworks that get released each month.

This is an incredible project. Just look at the popularity of streamlit. There is a giant demand to quickly standup python applications with a web front end.

- "WASM is great because it allows near-native performance by skipping the js interpreter"
- "Let's use it to run a python interpreter!"

A few concerns: Loading time, downloading dependencies every time instead of caching them.

Security: For example you showed it using open ai, surely anybody could view the source of the page and steal your api key.

I'm not sure I see the point just yet, though capable it's still using js and there's no way around that I guess.

[Eltrissi]

Really excited from the video. Thanks Patrick for the great intro.

Looking forward for more tutorials about pyscript🎉

[vonchilliman]

One thing I don't understand ids why PyScript is enclosed bewteen <pyscript></pyscript> tags instead of <script language="PyScript></script> tags? Why not use exisiting HTML language features to indicate a PyScript section.

Awesome video! The 2D game was one of my proof-of-concept apps. The game itself is one of the demos that's bundled with the Pyxel engine, with a few modifications like adding a mute button.

For what it's worth, experimental support for Pyxel is built into the current release of the Pyodide runtime (0.23), but I'd be a little cautious deploying with that at scale - because of how simulated infinite loops work in Emscripten (i.e. doing while(True) without locking everything up), some dead Python frames are left on the stack, leading to a slow memory leak.

It's definitely stable enough to play around with an have a good time - but watch PyScript and Pyodide for stability updates.

I’m not sure I’d use this very often. But, suppose you do data analysis or machine learning in python. With this you could just call the models directly. That seems nice.
And 100 million other applications. If you have other better tools you can use those, but it’s nice if people can use what they’re familiar with. Then again, it would have been nice if many of us happened to be familiar with the same stuff instead of having 50 choices. Maybe I can scribble together a new language and make everyone adopt that…

[SteveMcKeon]

@PatrickLoeber Lovely video and cool showcase, I look forward to exploring. *Important note:* I'd recommend reuploading with your ChatGPT API key blurred.

[waytospergtherebro]

If it doesn't have 12 billion dependencies that all break with every single update then it's never going to be able to compete with TypeScript.

[pedroserra]

WOW... Im new to this and this video gave me more clues to add to the scrypt and site im trying to build by self educating me... More videos like this please using PyScript and how to incorporate images on background, images on buttons, boxes that show images, calculators... that would be awesome for me to learn and get knowledge faster while listening to the videos and understanding the mechanics of this new world to me... Thank you so much Patrick cheers

[giannisnik]

Crazy Stuff!!!Unbelievable!!!!Next level Python!!!Thank you so much!!!

[BmxAddict]

i want to cry this is much soo much easier and understandable then sometimes javascript with their frameworks

[ihateidiots]

Why <py-script> ? Why not <script type="text\python" language="Python" > ?

[whiskeyfur]

About the only real use I see for this right now is to take RenPY games and host them on the web.
Most all the things you would want to use python for, aren't really intended for use on the front end but instead in standalone applications and on servers for heavy data processing.

[SreevathsaBV]

Awesome video! thanks. So, we can't currently deploy this in our custom domains? or can we?

[Godrose]

Looks interesting. What's its usefulness given the plethora of already existing frameworks that do this better faster easier?
