I am close enough to finalizing PEP 495 and its reference implementation, that it is time to have some bikeshedding fun and pick the name for the new flag.

This is a valid concern and even short experience with datetime.first shows that in the most cases the needed value is (not first). In the early versions of my proposal, I was using a "which" variable with values 0 or 1 as some sort of index into the ordered list of UTC times that correspond to the ambiguous local time, but I soon realized that which=0 or which=1 are devoid of any mnemonic meaning. I also wanted to have a true boolean flag with a meaningful name. The best I could come up with was time(1, 30, first=True) to stand for the "first 01:30" and time(1, 30, first=False) to stand for the "second (not first) 01:30". I did want to have a flag with the opposite meaning, but for obvious reasons, we cannot have a flag called "second". I also rejected "later" because I can never remember when to use "later" and when "latter" and since either of those words could be used as the name of the disambiguation flag, using either of them would be a disservice to our users. After I published the first draft of the PEP, I realized that the second of the two ambiguous hours can also be called "repeated." As I am writing this, I really have no objections to time(1, 30, repeated=True) spelling for the "second 01:30" other than having to make several dozen changes to the PEP and to the implementation code. If I have to make a name change, I would really like to make it only once. So if you hate the first=True default - speak now or forever hold your peace. _______________________________________________ Datetime-SIG mailing list [email protected] https://mail.python.org/mailman/listinfo/datetime-sig The PSF Code of Conduct applies to this mailing list: https://www.python.org/psf/codeofconduct/
