gh-91247: Performance improvement in list repeating by thatbirdguythatuknownot · Pull Request #92286 · python/cpython
Please stop pushing completely unverified code. Make it work, then submit the PR. A handful of commits in a given PR are not unreasonable, but seven commits in the space of minutes, most of them not even high enough quality to compile, let alone work correctly, does not a good PR request make. Make something that works and you're mostly confident of, minimize the number of changes not required to implement the fix (no pointless/harmful shoving assignments in the middle of larger expressions), and squash the commits down to just one or two for the bulk of the actual work.
I know that, but I usually can't verify it because I make changes on the desktop website (I don't know how to use git).
