That's a good start, at least. > I don't think it makes sense to also allow "-VV" - we're not > requesting the version twice, we're asking for more verbose version > information. It's not as far-fetched as you might think - if "vv" means "more verbose", and "qq" means "more quiet", then "VV" means "more version info". It's a form of word doubling for emphasis, a tradition that dates back at least as far as ancient Hebrew, and has some currency in English. And if -VV has no other meaning, it's not going to hurt to accept it as an alias for -Vv, right? Remember, this option isn't only for the expert - it's also for the novice, who might be typing at the dictation of someone else ("can you tell me what python -vV says, please? -- no, that's one capital V and one small v -- no no, not both capital, just one"). But if it can't be done, so be it. At least with them being independent flags, the order doesn't matter. > Since "-v" is already a counted option, we're also free > to expand it to give even more info the more verbose we ask it to be > (although initially I think pursuing just Inada-san's main suggestion > of matching the REPL header makes sense) Sure, I guess. Not sure what -Vvv would mean, but okay. The same could easily be done with -VVV though, just by making -V a counted option. Logic could simply be: if Version: # Count verbosity based on -v and/or -V Version += verbose if Version >= 3: print("info for -Vvv") if Version >= 2: print(sys.version) if Version == 1: # subsumed into the above print(sys.version.split(" ")[0]) ChrisA _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
