Want to do web server development? Flask, Django, Tornado, etc... can do that. Probably not as concurrently as Go, but it'll do.
Scientific computing? Its no Matlab, but the syntax is easy and the time you lose in processing you make up for when developing.
Desktop computing? PyQT is pretty good. Electron may be faster to build with, C will be faster at runtime, but Python, even with Tkinter, is ok.
Functional programming? There are list comprehensions, map, reduce and filter. Not as good as Haskell or Lisp, but it'll do.
Python isn't the killer language for any of these really, but its good enough in almost all cases that you'll be very productive and can iterate to a good MVP quicker than with most other languages.
