PEP 3103 (switch statements): inconsistency between a list and references to it

[ericvsmith]

In https://www.python.org/dev/peps/pep-3103/#option-3 there's a numbered list of options for handling case statements outside of functions.

However, the following text refers to these list items by lowercase letters, not by number. I think the list should be changed to be identified by lowercase letters. There are already too many numbered options in the PEP.

Go and submit a PR. However, if you're thinking of reviving this PEP, contact me first; I am in the midst of a design for pattern matching.

I don't intend to revive the PEP. I was just reading it because it was referenced elsewhere and I thought I'd refresh my understanding of what position the PEP took, and how it might relate to pattern matching, which I think is more useful. Glad to see you're thinking of pattern matching.

I noticed the error and thought I'd create an issue while I remembered it. I might just mention it on the mentors mailing list as a super-easy issue in case someone there is looking for something easy to get their feet wet. Although maybe not: since it's not the normal cpython workflow in this repo, maybe it's not a good example for a beginner.

Hmm, this exceeds my ReST knowledge. The source already uses (a), (b), etc., but when displayed at https://www.python.org/dev/peps/pep-3103/#option-3 they show up as 1, 2, etc. So someone who knows more about it will need to fix this. I'll leave this issue in case someone wants to give it a shot.

It looks like a CSS problem. The bulleted list has

<ol class="loweralpha simple">

s I'm guessing there's no CSS style for that (and hereby my CSS knowledge is exhausted).

list-style or list-style-type needs to be lower-alpha or lower-latin abc:

https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-type

The style for the <ol> is indeed list-style: lower-latin (right click and inspect in the browser):

However, the style that's applied to the <li> in the browser is list-style: decimal:

Changing it in the browser to lower-alpha or lower-latin shows abc:

https://developer.mozilla.org/en-US/docs/Web/CSS/list-style

---

pep.css contains:

ol.arabic {
  list-style: decimal }

ol.loweralpha {
  list-style: lower-alpha }

ol.upperalpha {
  list-style: upper-alpha }

ol.lowerroman {
  list-style: lower-roman }

ol.upperroman {
  list-style: upper-roman }

Looking at the source of https://www.python.org/dev/peps/pep-3103/#option-3:

    <link href="/static/stylesheets/style.30afed881237.css" rel="stylesheet" type="text/css" title="default" />
    <link href="/static/stylesheets/mq.eef77a5d2257.css" rel="stylesheet" type="text/css" media="not print, braille, embossed, speech, tty" />

The first looks like minified pep.css and the only with list-styles:

ol{margin-left:1.5em}ul{list-style:square}ol{list-style:decimal}ol ol{list-style:upper-alpha}ol ol ol{list-style:lower-roman}ol ol ol ol{list-style:lower-alpha}nav ul,menu ul,.menu,form ul,.errorlist,.text form label+ul,.sidebar-widget form label+ul,.tabs{margin-left:0;list-style:none;list-style-image:none}

Putting that through a prettifier:

ul {
	list-style: square
}

ol {
	list-style: decimal
}

ol ol {
	list-style: upper-alpha
}

ol ol ol {
	list-style: lower-roman
}

ol ol ol ol {
	list-style: lower-alpha
}

Which doesn't quite look right... Is there something broken in the minifier?
