Last thing first, I develop small Python tools at work, so your chance to evaluate them is unbelievably close to zero. Python itself is a C-type cancer full with case sensitivity and equal signs used to mean let it be equal. Together with limited base number types, it is intended to destroy the financial and the statistical industry.
And with it's legendary energy efficiency, now our planet, too.
But let's see my original points.
Disqus
1. It notoriously messes with webpage content copied into a reply. Even after you manually killed the double line spaces, random line endings, the posted content may be different from what you have seen in the editor. What you see is what you get...
2. Good luck to jump to the thread from their site to the website, if the site uses their hide comments and comment pagination functions. Firefox/desktop at least two buttons, Chrome/mobile much worse
Instagram
It offers the stories of those you follow. One story can be multiple pages. One of the followed persons share 10+ pages of menstruation cycle calibration. Good luck skip the rest of the story and continue with the next person's story.
YouTube
1. It offer some social media website like functionality on the start screen, the "Latest YouTube posts" section. Good luck scan through them, especially they are organized into multiple rows. Computers are good at repeating things, like "pressing" back, down arrow, scroll, click next, aren't they?
2. Good luck trace back which post is answer to which post in a heated comment section, where ~10 commenter wrote 10-20 answers per commenter...
Pinterest
They send you an email about something their algorithm thinks could belong to one of your tables. You go visit them, choose one, then press the left arrow next to the picture. Good chance they will refresh your feed with new ideas (basically the home page) instead of going back to the collection offering.

So... your main arguments against Python are:
- you don't like the syntax
- you don't like any example sites that I've mentioned
these all sound like "you" problems, not "python" problems 
------------------------------------------------
If you say that getting the money
is the most important thing
You will spend your life
completely wasting your time
You will be doing things
you don't like doing
In order to go on living
That is, to go on doing things
you don't like doing
Which is stupid.

Yes, syntax is awful.
"base class library" is more awful.
Especially for cross-platform development.
Don't trust me, just check the solutions for handling a key press without hanging while a key pressed.
Or executing an external command, and waiting for the result - now with bonus timeout from the blue!
Oh, and don't forget that deleting a non-existing file is an exception! Except when 3.6+ you unlink a non-link, because it 1) deletes the file 2) there is an argument for not throwing an exception for non-existing files 
Python is good for the Cool Kids to reinvent the wheel instead of solving real problems. Hence Guido is a good fit to the Outsourced New Microsoft.

Plenty of people who are super-stuck on "whitespace matters" have this opinion - I used to until I realised that it doesn't have to and the structure of python makes all python code look very similar - no brace wars, the requirement for self on class methods makes the way all OO methods work suddenly very clear. But to each their own - whatever language you could bring up as beautiful, I guarantee I can pick it apart too.

I don't follow here (especially in the context of a web app) - I've found Python to be very good for exactly that - cross-platform dev.

Stuff I'm finding for CLI tools is pretty-much how one would do it in many other languages (https://www.delftstack.com/howto/python/python-detect-keypress/) - if you're talking about blocking in some GUI framework, you'll have to be more precise because that's up to the framework (eg Qt), not python.

If you're using os.system, you're delegating to the underlying libc implementation - not python's fault if it times out - rather use subprocess as documented in many places.

This is pretty-much standard behavior in many programming languages - even though the final result is the same (the file isn't there after the call), it may be important to know that. Easy fix: test first, delete if present.
I don't see the point in responding to your last comment - it brings nothing useful to the discussion and merely exposes that you're aiming to hate on Python (and, probably any other tool that isn't exactly how you'd expect it to be) irrespective of the good points. It's like hating a screwdriver for not being a spanner.
Python is great for a large array of applications, not least of which is machine learning. Python is one of the two languages I suggest to new programmers to learn (either that or JavaScript - the former because it teaches good patterns and the latter because it's even more ubiquitous). It really sounds to me like you didn't try to get into the "pythonic" way of doing things - rather trying to make Python be whatever you expected of it. This is a common error many programmers make when trying to use any framework or language - and your response that Python is broken because it doesn't conform to your expectations is the typical response of the poor craftsman blaming his tools.
I really hope that you take the time to stop hating on it and rather love it for what it can do. No tool is perfect - Python included - it's best to use tools for the tasks they are good at and accept when they are not good at it. Python is good for myriad things, including the OP's question about web development, but, like any programming language, you'll get the most out of it if you're not trying to hammer it into the shape of the language you last used, but instead use it to learn new ways to do things - that you can take back to the bread-and-butter language you use as a daily driver.

I don't hate it just don't love it. All the exciting stuff - really nothing new under the Sun. AI? Do you remember that 90's newsreel showing how a film scanner found a dug-in Serbian tank on a film made by a drone?
Implicit Self? Nothing new for a Delphi developer - but why not implicit result variable for a function?
Yes, you can import a lot of externalies to have a basic INKEY() from the ZX Spectrum BASIC 🙂, but your mileage may vary when the multiplatform targets are Raspberry, CentOS and Windows.
Subprocess handling is vanilla subprocess. With the second timeout event when it can't kill it...

you're welcome
you'll find that opinions are like assholes - everyone has one and most of them stink
make your site in django - it's a perfectly legitimate way to do it
don't listen to people who have blanket opinions about tech (php and vb ruled the software world for ages - but apparently everyone thinks they're rubbish?)
use what works, not what people tell you you should be using - if those are the same things, well, that's just an interesting coincidence.

You should use the right tool for the job, which may indeed be python.
Some will say "python is slow". Compared to what? yes if you were trying to serve 1 million concurrent users over a 1tb internet feed using a JSON database, but if all you want is a small ecommerce site with links to a SQL backend etc, then - on modern hardware - your pipe speed will be more limiting than python, unless you are running it on a very underpowered PC with very limited memory etc.
I have an interactive card payment system running in Python, plus a guest sundry supplies/services ordering system designed to run as a web app on Android and iOS phones. It can't render a film like SHANG-CHI in 4K+3D in under 3 seconds FFS!, but it can handle multiple concurrent users over a 1Gb pipe, plus talking to the bank card payment system and a SQL backend, despite being run on a small virtual machine hosted on ESX.
Remember, these days, by the time you've developed your multi-user. high throughput web host using the latest HTML5/<language of="" choice="">/<framework of="" choice="">, the framework will have had at least 3 updates, been deprecated or significantly changed or just gone out of fashion in favour of the latest of the 200 or so new or revised frameworks that were released during the previous 3 months!
Find a well-known, long lived toolset that is in widespread current use for your dev. The latest 'shiny' is just a distraction!

Thanks for the reply, I think.

I grew up with BASIC. I am still maintaing customers who are successfully running on programs I created with it, since 1984. GoTo is just another tool and works great, if you use it properly. If you use a saw in an improper manner, you will wind up bleeding.
I don't undestand why younger "trained" programmers hate it so much.

I’ve used it for small websites used internally within the company I work for. Was fine.
I’d start with something like Flask, as it’s quite minimal, although you might prefer a larger framework like Django.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

You are the second person to recommend Flask, so I'm thinking it must be pretty good.

WTF, no contest.
The way in - the only way in or out - is at the front, which hinges on one side.
And ... there is no reverse gear. Drive too close the the garage wall and you are there for the duration!

According to the guy in the video and the illustrations of the gears there is a reverse gear.
The video was funny, he came to a hill and it refused to move about half way up.
It also has a sunroof for those times when door is not an option.

Are the drivers still asshats?
I'm a cyclist, and I ride the roads on my commute to/from work. I've found that there are two groups of drivers who have no compunctions about crowding you when you're on a bike: red pickup trucks (any make) and BMW drivers (all models and vintages)  .

I have a mountain bike I bolted what is essentially a chainsaw motor to and I would use it to get groceries in the summer.
People in cars are scared of it. It's loud and I can make it belch clouds of white smoke if someone gets too close.
I haven't used it over the past couple of years though. I probably need to change out the gas tank, and it needs some minor work done besides.
