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.

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.

After tearing my hair out writing JavaScript the last few days how close are we to Python in the browser?
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.

Graphs in Python web app
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.

Why you should start profiling your application on the production
It's basic, but it works. You can see what function or 3rd library is after your resources and debug them locally (For example, by using ClinicJS - https://clinicjs.org/)

7 Best Tools for Monitoring Node.js Servers
Clinic.js includes three tools to help diagnose and pinpoint performance issues in Node.js applications. It’s surprisingly easy to use. All you need to do is install the module from npm and run it. This will generate reports for you that make troubleshooting much easier.

GraphQL Fastify vs Apollo Server — Learnings from the real world
To compare the two servers, we used two packages. The first one was ClinicJS, an open-source set of tools used to diagnose NodeJS performance issues, which also gives you suggestions and points you in a direction to fix the diagnosed problems. The second one was hey, a CLI tool to send some load to the server. Below we show how we use them and the results of these comparisons.
