The infrastructure runs everything already in Python3, so this is mostly a clean-up. For MB, a python2 holdover was removed and new lint errors were fixed. The renames were automated with: git grep -e "/usr/bin/python$" | cut -d':' -f1 | xargs sed -i 's/#!\/usr\/bin\/python$/#!\/usr\/bin\/python3/1' and git grep -e "/usr/bin/env python$" | cut -d':' -f1 | xargs sed -i 's/#!\/usr\/bin\/env python$/#!\/usr\/bin\/env python3/1' Bug: v8:13148 Change-Id: If4f3c7635e72fa134798d55314ac1aa92ddd01bf Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3811499 Reviewed-by: Liviu Rau <liviurau@google.com> Commit-Queue: Michael Achenbach <machenbach@chromium.org> Cr-Commit-Position: refs/heads/main@{#82231}
