IPython terminal would display a string with \n in the same line, how to change this behavior?

given a snippet in IPython terminal

s = 'AAA\nBBB'
s

it would give 'AAA\nBBB' as output.

I have to call print(s) to get

AAA
BBB

Is there some config to make IPython's display to show the \n in a string as linebreak?

Jupyter Notebooks on EC2 Windows Instance

I have googled this for a good hour now and can't find any mention of running Jupyter Notebooks on an EC2 Windows Instance - specifically running Jupyter after remote-ing into the machine.

1 - Is this possible?
2a - If not - why not?
2a - If not - what is an alternative notebook that will work on an EC2 Windows Instance?
3 - If so, any one know of a guide to get it up and running somewhere?

Thanks in Advance.

Text Corpus Tagging System

I have a feature idea for an app I'm helping develop, and I'm wondering if it makes sense before I go too deep down the rabbit hole.

I want to find a way for a front-end user to edit a large text document and add a custom ID tag to a certain section of text of arbitrary length. My initial idea is to store the text as HTML and use a WYSIWYG editor with most of the functionality disabled, and just leave the ability to highlight a range of text and choose an ID attribute from a pre-defined list to add to a <span> tag or something like that. Would that work? If so, any recommendations on a WYSIWYG editor that would work well with this? Or is there a better way to accomplish this?

SSL certificate

My django app on an EC2 instance works fine with http://IP.address. I also used Route 53 to link up with a domain and now http://domain.com works

But why does https://domain.com not work? The domain had been previously linked with an SSL certificate. HTTPS is allowed on my EC2s security group. Do I need another SSL ?

Real life examples of complex applications

Are there some good examples of real applications (not hello world todo/blog post or tutorials) of Flask applications, from where a new flask user could learn best practices from?

Flask doesn't force any design patterns or specific ways to do anything on me, and that leaves me wondering about what are the best ways to do something. How do I split up the routes file from all-routes-in-a-file.py to something more manageable, how do I validate input requests coming from a JS front-end, what are the best practices for doing thing X and Y, that I haven't even thought about yet.

Background information: I am writing a back-end api for a Vue frontend, there are no templates in the flask app, I am using JWT for authentication already. I think I don't need blueprints, because I don't have any templates to separate from the other things. I just don't want to bunch all my routes together in a huge file, like.. all the examples on the internet do.

I have found some open-source flask examples, but they seemed to be doing something weird, or.. were really outdated.

Or should I just write my back-end in Java and Spring, since that is used at work,

Django + async: delete from DB

Django version 4.1.2

I just used the following code snippet:

r = await mymodel.objects.aget(some_name=myname)
await r.adelete()

This fails with: "AttributeError: 'mymodel' object has no attribute 'adelete'

But this does work though:

r = await mymodel.objects.aget(some_name=myname)
await sync_to_async(r.delete)()

Any fix for this?

Choosing between options for presenting Plotly figures on a website (Python/Jupyter)

I'm looking to share some of my charts (Plotly) (on a Github webpage first and later on, on a personal website - not the notebooks, but the charts by themselves. I have spent a lot of time and found it surprisingly difficult to get started, and would very much like some input.

The options that I see would be the most relevant are:

1. Export from Jupyter Notebooks/labs to HTML - limited interactivity?
2. Dash
3. Panel/HvPlot

I have started out following a YouTube tutorial on option 3. This didn't present a way to actually show the plots on a website. For this option, the order of operations seems to be:

Python/Pandas -> Make plotly figures and interactive dataframes -> use HvPlot -> Use Panel (or similar) -> host this in Heroku/MyBinder/similar.

Am I on the right track here?
