[Python-ideas] Fwd: Re: PEP 472 - slices in keyword indices, d[x=1:3]

I attempted to send this yesterday, but used the wrong sender email address and it got rejected. I think this is still relevent, just to confirm I understand the proposal correctly. ----- Forwarded message from Steven D'Aprano ----- Date: Mon, 24 Aug 2020 11:46:02 +1000 From: Steven D'Aprano To: python-ideas@python.org Subject: Re: [Python-ideas] PEP 472 - slices in keyword indices, d[x=1:3] On Sun, Aug 23, 2020 at 09:40:53PM -0400, Todd wrote:

I think it is worth directly discussing the availability of slices in PEP 472-style keyword indices, since we seem to have mostly converged on a dunder method signature. This is an issue that has been alluded to regarding keyword-based (labelled) indices but not directly addressed. The basic syntax would be something like d[x=1:3].

I read that as equivalent to `d[x=slice(1, 3)]`. Is that your intention? If that is your intention, then a big +1. If your intention was `d[slice(x=1, 3)]` then I think you would have to justify what it means and why you want it. -- Steven ----- End forwarded message -----
