9.10. Generator Expressions

Some simple generators can be coded succinctly as expressions using a syntax similar to list comprehensions but with "parentheses instead of brackets"

Since parentheses comes under brackets, brackets could be changed to "Square Brackets"

In the above comment,

Line 1 is the URL where it needs improvement

Line 2 and 3 are the actual content in the page that needs improvement

Line 4 is the proposed solution

In British, Australian, New Zealander, and Indian English (and sometimes Canada), at least, "bracket" on its own typically means round brackets () and is rarely if ever used for square brackets [] or curly brackets {} without the adjective.

See for example https://english.stackexchange.com/questions/168762/brackets-vs-parenthesis for a discussion.

Consequently, the phrase "parentheses instead of brackets" reads to us as "parentheses instead of parentheses" would to Americans. In other words, weird and requiring a moment (or three) of thought to translate.

I support the suggested change to "parentheses instead of square brackets" -- it should read more naturally to people in the British Commonwealth and (I hope) shouldn't look too strange to Americans.

My personal preference would be for "round brackets instead of square brackets", but I guess that will be a battle I have no hope of winning *wink*

"round brackets instead of square brackets" sounds better.

Its simple and direct and doesn't require any extra operations other than the required one.

"round brackets" would require just as much thought (if not more...it's not a thing at all in American typographical language) for an American to understand as the unadorned bracket does for the rest of you, so the best compromise is "parenthesis instead of square brackets", since parenthesis is used elsewhere in the docs.

It looks like the docs job hung on the 2.7 backport, but I don't see how to restart it.

I clicked the "Details" link and restarted the build from there.
Closing and reopening the PR will also restart the build.

Thanks, Mariatta.  I did click on the details link, so either the restart link isn't obvious or I don't have the correct permissions to do a restart :)

And thanks Emily for doing the PR.
