@array There really is very little you need to go outside python for, so people don't.

Scripts? Check.
Well-factored applications? Check.
Static type-checking? These days, check.

It really is a wide range, and while it is not too performant, most of the time your code is waiting for I/O or a human. When performance is actually needed, heavy calculations go into pandas and numpy and on the other end things like protocol parsing go into gunicorn and starlette.

Python's got you covered. Best language for almost nothing, good enough language for almost everything. More boring than Ruby, less line noise than Perl.

@clacke Yeah, it's really pervasive. And very good at what's good, as I said, I like it too. It's just the point that you raise, "best language for almost nothing", that brings me some doubt. As in, why not just use "the best tool for the job", when there are arguably better options in some domains? Using Python for *everything* sounds just a bit... Lazy, I guess? :P

@array @clacke all the more reason to see its position as a very good prototyping language. Perfect for demonstrating what the final program should do, much of how it can work and good enough to use until the "production" replacement is completed.
