lexbor VS CPython

It supports both CSS selectors and XPath like Nokogiri, but with separate engines - parsing and CSS engine by Lexbor, XPath engine by libxml2. (Nokogiri internally converts CSS selectors to XPath syntax, and uses XPath engine for all searches).

An HTML parser, probably the simplest relatively modern example I could find is 1MB https://github.com/lexbor/lexbor (haven't used it, but might look more into it now that I know it exists.)

although I don't follow the need to have what appears to be two completely separate HTML parsing C libraries as dependencies; seeing this in the readme for Modest gives me the shivers because lxml has _seen some shit_

> Modest is a fast HTML renderer implemented as a pure C99 library with no outside dependencies.

although its other dep seems much more cognizant about the HTML5 standard, for whatever that's worth: https://github.com/lexbor/lexbor#lexbor

Heh, oh, new to the Internet, are you? :-D

Lexbor is here: https://github.com/lexbor/lexbor

Well, regarding HTML5, what I've found was libxml (does not support tag-soup HTML5), https://github.com/lexbor/lexbor, for which I was unable to find good documentation ( see https://lexbor.com/docs/lexbor/#dom), Apache Xerces (appears to not support tag-soup HTML5 as well), and Gumbo, which does not appear to be active and to support selectors and XPath (although there are libraries that add that).

I think we've all (mostly?) tried it. It really is the Wild West of the web when you're trying to parse other people's HTML, though.

I've played around with this parser which is extremely quick. https://github.com/lexbor/lexbor

I’m glad to have the opportunity to contribute to an open-source project that is used by thousands of people. Hopefully, we will speed up Nokogiri (or XML parser it uses) to match the performance of html5ever or lexbor at some point in the future. 800 ms to extract data from HTML is still too much.

I'm sure there are exceptional situations, but I'm struggling to see why any decent test would be interacting with private methods and variables. It would be like creating datetime() and then making tests that interact with the source code of datetime(). In this hypothetical situation, you should be testing the functionality of its date and time manipulation, not touching private methods like _format_time() or fromisoformat().

Can you explain a bit more about what you mean here?

> Is it even possible to implement your own `MutableMapping` or `dataclasses` equivalent type in Python?

Of course. With dataclasses that's what Python itself does; that's a pure Python module:

https://github.com/python/cpython/blob/3.11/Lib/dataclasses....

For MutableMapping, Python currently implements it as a C class for speed, but you could implement the same functionality in pure Python. That's what earlier versions of the collections.abc module did.

> I know the latter requires custom plugins.

I don't know what you mean here. See the pure Python module that Python itself provides above.

I don't think anyone ever claimed that this was something the Win32 API did. Java fro example exposes os.name, python has the mapping between version and release in its platform module. There have always been a million wrappers around the Win32 API that provided developers with the platform name.

My advice would be to look for a boothcamp option. As in a job posting that provides you with the needed training. Or watch a few videos on YouTube, do your research to see what you want to do (what kind of software development) and then ask a more specific question here. Or go to https://www.python.org/ or similar site and start working on something. There is a lot of documentation out there and it's not the lack of resources that's the problem. I think you're a little confused and overwhelmed by the options which is normal. If you keep at it, it will pay off just like anything but don't expect too much from the field right away.

when the post says to put it into a folder with Python and Python's files, it means you gotta download Python. yeah, the coding software Python. so download the latest version of Python, and put it in a neat little folder with convert_pygm.py and your .json files, like this

Python is a powerful and versatile programming language that has become increasingly popular. For many, it’s one of the very first programming languages they pick up when getting started. Some of the highest traffic posts on my blog many years after they were written look at using C# and Python together. Today we’re going to explore how you can use Python from inside a C# .NET Core application with much more modern approaches than my original articles. Enter Pythonnet!

Unreal Engine has a very steep learning curve, and I do not recommend it for absolute beginners. What your stepson should do first is download a programming language like Python (https://www.python.org) and start learning the basics of coding via free tutorials. Or, if he prefers 3D art as you say, perhaps you should introduce him to Blender 3D (https://www.blender.org). Both of these applications are far easier to learn and can run on nearly any computer, so don't worry about purchasing an expensive workstation right away.

I am absolutely sure about the we need a lot of smart and enthusiastic Python programmers, who especially have knowledge in:
