Closing this out on my end — master's sorts/bubble_sort.py already has the Comparable/TypeVar pattern this was aiming for (someone else's contribution landed it, and the checklist on #15234 already shows this file checked off). I'll leave this closed rather than rebase against a change that's now redundant.
