I don't think the iframe will work very well for multiple reasons:

• The scaling problem that you already encountered. iframes are notoriously hard to scale, as the size has to be hardcoded when embedding them.
• The nested presentation will have its own navigation, so it wont be clear where to proceed with the presentation.

You also already anticipated teh next problem - when putting the same video on multiple slides indeed the video will "restart" - first the old video will fade out and then the new copy will fade in. This is because each slide is it's own self-contained HTML element. So this also won't do what you want.

Instead I would propose to use Fragments. Fragments are the way you can have individual elements on a page change without changing the whole slide (commonly used for making bullet points appear).

In your case you can implement your "sub slides" on the left side as individual fragments that appear on top of each other using the css classes fragment fade-in-then-out (to make them appear/disappear) and r-stack (to make them appear on top of each other). You can see an example on the "Layout" page in the documentation (the second one with cat pictures).

If you put all of your sub-slides as fragments, then you can just have your video embedded as normal on the right and it will play independently from the subslides changing. Once the last sub-slide is passed, the presentation will move on to the next real slide (stopping the video).

Can you please check the below code? Hope it will work for you. You need to add style for li like below:

Actually this small adjustment does the trick

I found the problem, it was a DNS issue. I discovered my AT&T phone was using DNS service by "sbcglobal.net" (AT&T's default DNS server). That DNS server returns an IP address even for a non-existent name. In particular, it returns an address belonging to "akamaitechnologies.com" (whatever that is). Since that is an existing site, http connects and getResponseCode returns 200. Since it cannot serve my requested file, the download fails.

When I set my phone to use a DNS of "dns.google" (8.8.8.8), everything works as expected.

This type of DNS spoofing is a Bad Thing because many apps depend on an Unknown-Host-Exception to detect an incorrectly entered domain name, e.g. in an email address.

The end goal is to hide Wi-Fi icon from menu bar.

UI Scripting of System Preferences in macOS Big Sur has become a nightmare, as many of the methods that used to work in previous versions of macOS just no longer do in macOS Big Sur. Many UI elements report Parent does not report element as one of its children when using Accessibility Inspector of Xcode, which then make it impossible to communicate with them. Or some code may work one time and then not the next. I wrote some code that opened to Wi-Fi and clicked the Show in Menu Bar checkbox. It worked a few times and now it doesn't.

The original code I wrote which sporadically worked I'll not post, however, the following example AppleScript code does consistently work as tested under macOS Big Sur 11.4, albeit it is what I consider kludgy UI Scripting, as it's visible on screen, is prone to failure due to timing issues, or if the hierarchical UI element structures change due to macOS updates/upgrades.

The example AppleScript code, shown below, was tested in Script Editor under macOS Big Sur 11.4 with Language & Region settings in System Preferences set to English (US) — Primary and worked for me without issue¹.

• ¹ _{Assumes necessary and appropriate setting in System Preferences > Security & Privacy > Privacy have been set/addressed as needed.}

This script requires that the Use keyboard navigation to move focus between controls checkbox is checked on the System Preferences > Keyboard > Shortcuts tab, and as coded, the script checks its status and toggles the checkbox, as necessary, based on its current status.

This script also first checks to see if the Wi-Fi icon is shown on the Menu Bar and if not, then halt execution of the script, as its purpose is to act only if it is shown on the Menu Bar.

You have to rename it inside change_table if you want it to work as you are using it now.

without enumerating all of the nested tags manually.

That's not possible.

One fundamental restriction of SQL is, that the number, data types and names of all columns need to be known to the database before the query starts executing. SQL can't do this "at runtime" and change structure of the query based on data that is retrieved.

You can extract the content using xmltable() - but as explained, there is no way without specifying each output column.

It seems to me that what you need is a pattern called memoization.

There is a functools.cache decorator (for Python < 3.9 you can use lru_cache) that you can use this way:
