Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

You are right for the most part. I attended a talk about pyscript[1] (runs python in the browser using wasm which is similar) and there is a 2x performance hit.

Python HTTP library 'urllib3' now works in the browser
PyScript maintainer here - I'd love to hear more about this application! Either here, or over on our Discord (invite link is on the GitHub Page [1]).

Convert code from alpha version to latest version. Where to find complete and precise changelogs?
For the first question - why your code previously created an HTML node but now just prints out the literal characters of the HTML - that was a change made in 2022.12.1, in Pull Request 915 to be specific. You can check out the single-line change that caused this, if you want. Essentially, calls to Element.write() or display() have their contents escaped by default, which wasn't the case before.

How to access py-click from py-script?
Note that in the current release (2023.03.1 at time of writing), py-[event] listeners are only hooked up once at page-load time, so changing that attribute after the page loads won't do anything. In the upcoming release, py-[event] handlers are dynamically attached and managed each time a py-[event] attribute on the page is changed. (PR 1435)

After tearing my hair out writing JavaScript the last few days how close are we to Python in the browser?
PyScript started as a usability layer around Pyodide for those not used to working in JS. It's now working on things like incorporating the Micropython runtime as an alternative, moving the interpreter to a worker thread, adding a plugins ecosystem, easier events API's, and more.

How does PyScript work with 3rd party JS libraries, like Three.js ?
You can also check out the WebGL demo from the PyScript examples, which uses Thee.JS.

NameError question
Mainly, the pys-onClick syntax that was present in earlier version in favor of the new py-* syntax, where * is a browser event name. It also takes a string of executable python instead of the name of a Callable. So in your case, you'd use py-click="get_input()". (There's a long-in-progress PR on GitHub with more examples.)

How does PyScript actually work?
This is the primary difference between Pyodide and projects like Transcrypt or Brython: rather than transpiling to JavaScript, you get the real-deal CPython interpreter running client-side in the user's browser. There are a few things that don't work out of the box, since CPython usually runs on a computer and the Browser environment has some unique restrictions (lack of low-level access to networking, for one), but most things do just work.

alternatives to the javascript ecosystem
In the past, I've personally used GWT to transpile Java to JavaScript in order to share some complex code modules that we needed to use on both the server and client for an enterprise application. In more recent years, I've been using Transcrypt to develop React/MUI applications that are coded in Python. So I'm able to use JS libraries that are proven to work great in a web browser, but use my preferred language to code to the API of those libraries. This approach is certainly not for everyone, but it can be a viable option in some cases.

What's your Python story?
I now use Python everywhere. Desktop (PySide), embedded (MicroPython), web dev (React via Transcrypt), mobile (Kivy), and just general scripting. I love the versatility of Python, the ease of reading it without the visual cruft of other languages, and the availability of existing libraries that do just about everything you can think of. I also agree with the OP on the welcoming attitude of the Python community. The fact that Python is used in so many different areas leads to many new learning experiences when talking to other Python developers.

Transcrypt is pretty usable for this.

What do you guys use python for?
Transcrypt transpiles Python into JavaScript in the same way that TypeScript gets transpiled into JavaScript. It lets Python code word with JavaScript libraries that can then be run in a web browser.

There are options for writing Python and transpiling it into JavaScript but, frankly, they suck (https://www.transcrypt.org/).

React JSX vs react with HMTL
Lol, I'll tell you but you're not gonna like it - I write React applications in Python using a Python-to-JS transpiler called Transcrypt, and the source needs to be valid lintable Python code, so no JSX.
-
What is the best way to parse python code?
The Python AST module exists for this purpose and works by tokenizing individual pieces of the source code. It's also how transpilers such as Transcrypt work their magic to convert Python code to other languages.
