Since you know Python, do you find Gonas expresive an clear as Python?
Is there anything like list comprehensions and generators in Go? And anything simple like the Flask web framework?
How does it compare to deploying a python app using uwsgi+nginx in terms of performance / reliability?
There are no list comprehensions, but they're just trivial loops, anyway. Generators of a sort can be created, but are not commonly used. There are several web frameworks, I don't know flask, so can't answer if any are like that, but even with just the standard library you can trivially put up a web server that has routes and responds appropriately, plus json and html & text templates are in the stdlib too.
Deployment is where Go shines. You don't need nginx or a specific runtime, or uwsgi. You just deploy the file and run it. It runs its own web server. The web server is on par with nginx for performance, and is as stable as your code is (which is generally very stable, since Go's error handling is very explicit). And of course Go code in general is approximately 10x as fast as python.
