I think this is correct as is - isn't this supposed to show how the single quote doesn't get escaped? See text immediately following > I think this is correct as is - isn't this supposed to show how the single quote doesn't get escaped? See text immediately following

Yup, my bad - sorry @PSY27 . Though as Will said, if you change line 3818 to use an f-string, that would be good. In that case, you could add
```
ref #29547
```
to the pull request description instead of
```
#32039
``` @WillAyd @MarcoGorelli  please review it now
 thanks @PSY27
