If I was a python dev it seems like it might be worth learning but since I'm a web dev and already know a few frameworks I'm struggling to find a reason to teach my self flask.
Does Flask have any advantage over something like Angular?
I don’t know what you’d consider high traffic, but we have used and continue to use Flask in production for a variety of systems. Those include:
- providing the back ends for relatively large and complicated single-page applications;
- implementing more traditional web sites, with very little JS on the front end, which use Flask to do almost all of the routing and rendering; and
- implementing dedicated HTTP-based APIs for integration with third party services.
Flask is an excellent tool, and that is not a description I use for very much in the software world. It provides widely useful functionality, it has a tidy design and a reliable implementation, it’s well documented, and it imposes few overheads or unnecessary dependencies. If you’re purely a front-end dev then that functionality isn’t what you need and neither is Flask. If you’re interested in the back end as well, you could do a lot worse than to learn Flask.
There are two main features of Flask for me, over something like RoR: it's Python (my preference over Ruby); and it's a very light framework with a ton of modules, compared to my perception that RoR is pretty big and heavy and opinionated.
YMV, I only do this stuff in my evenings so I'm not terribly familiar with it all.
That's because Flask is simple. You advertise RoR when you want somebody who doesn't need to spend a lot of time learning Rails. But nobody needs to spend a lot of time learning Flask.
That's also a drawback of Flask, in that you have to build or add more to get the same higher-level expressiveness of something like Rails. But if what the project needs is a relatively low-level web framework, it's a fine, easy-to-learn choice.
Uber uses Flask & Nginx for part of their site.
The 2012 Obama campaign team (who really shook up the use of internet & tech in campaigning) used Flask too.
Mailgun uses Flask for their API (reported). Stack is verified here, but no details given: http://stackshare.io/mailgun/mailgun
Angular = Front end
Bizarre you are comparing them. Suggests you have not used either.
I have no idea where you are looking for jobs but where I am demand for Flask and Django are booming and there is a shortage of them.

> They started with Django but moved out of Django and currently use 'home grown framework on top of Flask'.
> Presently, the API does over 12 billion requests per day, all in Flask.
Wow, that is 138kqps. Not something that would strike me as your typical Python workload.
I don't know if it still is, but when I was at Mozilla the service that every instance of Firefox around the world hits to do the version/extension-compatibility checks was backed by Django, and was at something like 15k req/s served. Firefox has gained some market share in the four-ish years since I got that number, so probably larger now.
You should be comparing it to micro web frameworks like Nodejs' Express, Ruby's Sinatra, PHP's Slim, Java's Spark, etc.
