Re: 转发: How to exit program with custom code and custom message?

[Lars Liedtke]

I totally understand your reasoning here, but in some way it follows the unix philosophy: Do only one thing, but do that good.

And exiting is something different from printing to STDOUT or STDERR. Yes sometimes you want to print something before exiting. But then you should do that explicitly and to the output you want and not implicitly rely on adfdtitional parameters of exit. Yes, not all functions work this way. But that does not mean they shouln't ;-)

Cheers

It doesn't actually take a list of arguments; the square brackets

Oh, I see, it seems that I mistunderstood the document.



but for anything more complicated, just print and then exit.
It's worth noting, by the way, that sys.exit("error message") will
print that to STDERR, not to STDOUT, which mean that the equivalent
is:



Yes, I know, but don’t you think if `sys.exit` can take more parameters and have a default output channel selection strategy will be better?
Thanks.
