gh-67748: DOC:Add summary table for str methods in stdtypes.rst#1709

csabella · 2017-05-22T00:54:42Z

Based on the original patch by Martin Panter to create a table categorizing str methods.

https://bugs.python.org/issue23560

Issue: Group the docs of similar methods in stdtypes.rst #67748

vadmium

I don’t have much of an opinion about adding this table comparing the methods that are available. If others think it would be good to add, don’t let me get in your way :)

FWIW I don’t think it helps with Ezio’s original goal to remove duplication and make the documentation shorter. But I don’t see a good way to accomplish that and at the same time satisfy @rhettinger by keeping an entry for each method in alphabetical order.

Is this paragraph necessary? It seems obvious just given the section and table headings.

Thanks, Martin. You're right. I wasn't quite sure where to place this overall and thought there would probably be suggestions, so I kept it vague. There wasn't a section that combined both text and binary sequence types before and I didn't know if people would like having str and bytes (and bytearray) types all in one table or if there should be a separate table for each one under the existing sections.

csabella · 2017-05-27T11:57:03Z

@vadmium Thanks for your comments. I hope others chime in. Being fairly new to Python, I've found my chart (or your changes) very helpful in using the right str functions. To your point, it didn't really do much to shorten the page though.

Maybe __mod__ (%) should be included here too.

I've added some lines for the printf-style and for f-strings. I think I linked them to the best places for a description.

I think the leftmost + can/should be a |.

Perhaps the methods and their corresponding rmethods could be combined on the same line to make the table more compact. If however the end result isn't more readable, you could leave them separate.

I added the methods and rmethods on the same lines, but I did it 2 different ways so that you could pick which one you prefer. find\rfind and index\rindex are done as columns while split\rsplit, ljust\rjust, and lstrip/rstrip are done as or.

Was this change intentional?

Thanks for catching that! I've removed it.

This is how the (first half of the) table looks like. The table intentionally splits some cells and uses a | on others to show two alternative styles.

One issue with the table is that it takes over a page and it has a lot of whitespace. Maybe we could do something that looks like this instead (using a proper colspan):

	Searching and Replacing
str	`str.find`/`str.rfind`, `str.index`/`str.rindex`, `str.startswith`/`str.endswith`, `str.count`, `str.replace`
bytes	`bytes.find`/`bytes.rfind`, `bytes.index`/`bytes.rindex`, `bytes.startswith`/`bytes.endswith`, `bytes.count`, `bytes.replace`
	Splitting and Joining
str	`str.split`/`str.rsplit`, `str.splitlines`, `str.partition`/`str.rpartition`,`str.join`
bytes	`bytes.split`/`bytes.rsplit`, `bytes.splitlines`, `bytes.partition`/`bytes.rpartition`, `bytes.join`

We lose the direct mapping from str to the equivalent bytes method, but since they are still grouped it's easy enough to find it.

CAM-Gerlach · 2022-08-31T04:31:02Z

Hmm, well take my opinion as just one data point, but while I do definitely see the concern of it being rather long, at least from what I can see so far, I find the current format a good deal easier to skim and consult as a structured summary, at least personally to my eyes. If we're going to go with a structure similar to what you propose, I'm not sure if we even need a table at all, as opposed to just a bulleted list, which has essentially the same structure, is even more compact and is simpler to read and write, e.g.

Searching and Replacing
- str.find/str.rfind, str.index/str.rindex, str.startswith/str.endswith, str.count, str.replace
- bytes.find/bytes.rfind, bytes.index/bytes.rindex, bytes.startswith/bytes.endswith, bytes.count, bytes.replace
Splitting and Joining
- str.split/str.rsplit, str.splitlines, str.partition/str.rpartition, str.join
- bytes.split/bytes.rsplit, bytes.splitlines, bytes.partition/bytes.rpartition, bytes.join

Meanwhile, the original table could be made more compact and maintainable, at least in the source, by formatting it as a list-table rather than a full literal table.

Also, of the two styles, FWIW a real cell split rather than a raw | looks a lot cleaner and clearer to me.

@ezio-melotti I'm going through and rebooting and/or closing old Docs PRs. This one looks good and is an improvement over not having it. Would you be cool with merging? There would always be the option to iterate on it in the future. Thanks!

I agree that it's an improvement and can be iterated on.
If there are no objections, I'll merge early next year.
