The common approach of slicing with [:-len(suffix)] is wrong when the suffix is empty; the slice will produce an empty string, whereas the expected behaviour is to produce the original string unchanged ("removing" the empty suffix). Although uncommon, such a case can arise when dealing with programmatically-generated suffixes, and there's no indication that the function requires a non-empty suffix to operate. I've added a test case but am unable to edit the existing implementations. The easiest fix is to add a check that the suffix is non-empty. nneonneo talk 21:37, 6 December 2023 (UTC)๐‘„ก๐‘„ฎ๐‘„›๐‘„ด ๐‘„˜๐‘„ฌ๐‘„š
