As long as we're talking about libraries, yes. For cli tools, on the other hand, there are definitely legitimate cases for exiting early.

- tomp 7y agoSure, but even in most of those scenarios, I’d prefer to structure the code differently... perhaps write a main() function that just returns, or other functions... more modular, maintainable, teatable, ... admittedly, in Python you need to use os.exit if you want to return a specific non-zero exit code, but even in that case good code style would be something like def main() blablabla if foo: return bar ... return 8 if __name__ == “__main__”: os.exit(main()) Of course that’s just my advice / opinion / preference, other ways are valid as well...
