b-decoded VS requests-html

Just use b

I use b

I used to believe this but i don't anymore.

Arthur is famous for his very dense programming style. Most C programmers would scream when seeing this code.

In his view (and others in the terse scene), it is much better to have everything in your application readable on the screen at once than to have great names for things or a lot of white space to comfort the first timer reader.

To them, once you've sufficiently studied that screen or two of code, you can understand all of it at the same time. If it's spread out over thousands of files, it's very difficult to understand all of it, which leads to bugs, unnecessary abstraction, and the need for advanced tooling just to work with your own project's code.

He wants to see the code "all at once" so he can understand all of its behavior without paging around and shifting his focus to another tab, window, etc. To get there he makes a lot of tradeoffs in terms of the code formatting and naming conventions. He also, in b, creates a dense set of interlocking macros and abstractions that can make the code very hard to follow.

Critics and the uninitiated say that his code is like old school modem line noise: random punctuation intermixed with bits of understandable code. I would suggest that he's actually quite careful with the abstractions he chooses and they are actually not always the most dense, highly compressed code structures available to him. He chooses wisely and his code rewards deep study.

Here's some links relating to this style of code that you may find useful:

They're not 1.5 paragraphs per line, but enough to give a taste of the implementation style.

I could write a whole compiler in that time.

requests-html

Ya, thanks for advice. When using requests_html library, I am trying to lower down the speed using response.html.render(timeout=1000), but it raise Runtime error instead on Google Colab: https://github.com/psf/requests-html/issues/517.

For dynamic js, prefer requests-html with xpath selection.

Example: requests-html which has a rather exhaustive README.md, but their dedicated page is not that helpful, if I remember correctly, and currently the domain is suspended.

When it comes to web scraping, the usual people recommend is beautifulsoup, lxml, or selenium. But I highly recommend people check out requests-html also. Its a library that is a happy medium between ease of use as in beautifulsoup and also good enough to be used for dynamic, javascript data where it would be overkill to use a browser emulator like selenium.

Quite possible. If you look at requests-html source code, it is simply one single python file that acts as a wrapper around a bunch of other packages, like requests, chromium, parse, lxml, etc., plus a couple convenience functions. So it could easily be some sort of bad dependency resolution.

What I do is try to see if I can use requests_html first before trying selenium. requests_html is usually enough if I dont need to interact with browser widgets or if the authentication isnt too difficult to reverse engineer.
