PyScript First Impressions - Run Python in HTML Document - RIP JavaScript

In this stream we will talk about a HUGE milestone for Python - The brand new PyScript framework! We will see a demonstration of how to use PyScript, how to combine it with HTML, CSS and JavaScript, and we will also test some of the features in this fun First Impressions tutorial.
Please keep in mind that PyScript is so new that they don't even have documentation at this point of time, so prepare to be extra creative and adventurous as we will try to figure everything out on our own.
After the demonstration I will of course stick around for some viewer questions and comments :)

How does it compare with Brython?

[@PythonSimplified]

Great question, Katrina! 😀 Brython is much faster and much more established at this point of time. The speed is similar to CPython and there's a really nice documentation with lots of code examples and tutorials: brython.info/static_doc/en/intro.html With that said, Brython is a bit limited in terms of combining Python libraries. It can only use libraries that are completely written in Python, so Pandas, NumPy, OpenCV and Matplotlib are not even an option unfortunatley 🙃 On the other hand, PyScripts' main focus is on those CPython libraries as it's the perfect combo for data science... it's just extremally slow at the moment and no one really knows how to properly use it! hahaha There's still lots of work ahead - but I'm really looking forward to see how it turns out! 😉

That's a great question. I'd like to give you a different answer than​ @Python Simplified :) "Quoting from it's own page (pyscript.net) PyScript is a framework that allows users to create rich Python applications in the browser using HTML's interface and the power of Pyodide, WASM, and modern web technologies. " It uses Pyodide (a Python implementation on top of WebAssembly) to run Python on the browser. Brython is another implementation of Python and in that sense, it's more fitting to compare Brython to Pyodide rather than Brython and PyScript. (one could actually try to make PyScript run on top of Brython rather than Pyodide but, imho, the cons would outweigh the pros) Now, to compare Brython and Pyodide: Brython transpiles Python code to JavaScript, so can handle some pure-Python libraries only. It does not have any features to support running binary code. Pyodide is a full CPython implementation in WebAssembly, and can use existing Python libraries (including those written in or backed by C), like NumPy, Pandas, and MatPlotLib. From the next release, it should actually be fully based on top of the main official CPython on WASM project (github.com/python/cpython/tree/main/Tools/wasm ), which means it'll basically be able to remove a lot of the patches it had to do. Both Pyodide and Brython are great projects just different and for different audiences. Brython is older iirc, but I wouldn't consider it faster or most established than Pyodide at this point. PyScript is higher level Framework on top of one of them and, yes, it's very very new. Hope this helps 🙂

[@diwakar_tsn]

Lol! I sleep before live 😆 See ya ✌️

[@manusoftar]

I can already invision lots of "slow like f*" websites based on this, unfortunately. The two main reasons why this approach for making websites is slow like f* are: 1.- Python itself is slow like f* 2.- Browsers don't offer nativa support for running Python code, this is some js library (which IS run natively on the browser) that somehow manages to run Python code, my best guess is that it uses some sort of cloud computing solution to emulate a headless terminal with Python where it runs the code and then captures the output and sends it back to the website. Like a virtual machine that has Python installed and does the execution of the code to then return the output of the execution to the js library which in time outputs it into the innerhtml of the py-script tag... I will definately stick to old and trusty JS!!

[@samferrer]

The future is not about any specific language ... it is about freedom of choice ...

[@PythonSimplified]

Agree a 100%!!! When it comes to options - the more the merrier! 😃😃😃 Now, finally, client side Python is also an option!

Can I build an entire site with pyscript?

[@cybersecurityexpert477]

Ma'am can we create app or website in python with mobile

[@PythonSimplified]

Yup, I was able to do so with Wayscript, they provide you a bash runtime even if you access their service through your phone - your code will run on their clouds rather than on Android 😊 And if you follow my most recent Flask tutorial: kzbin.info/www/bejne/rGSmhIShha-nd8U I also show you how to host your site with Wayscript there... but the only caveat is that you may not have enough free runtime to build an entire site, you may need to select a plan instead of using only the free features. Another option if you have a modern Samsung phone is to use DeX which turns your phone into a computer (I believe you get a Linux environment with it). Other than that, it's a bit difficult to create websites on the phone with code... but you can always go for Wordpress or Wix if everything else fails 🤷‍♀️

[@pwang99]

Yes, pyscript runs on mobile Safari and android. You can even add pyscript apps/pages to your iOS Home Screen as an app, bc iOS thinks It’s just a web page. 😀

Yup! I 100% agree with you, Frikkie! 😀 Brython is as fast as CPython, while PyScript is nowhere near that at this point of time! With that said - Brython cannot be combined with libraries such as NumPy, Pandas, OpenCV, Matplotlib, etc. ironically, anything written in CPython is not gonna work 😅 So Brython CPython in terms of speed but no CPython functionality.
