This migrates old python2 dict.iteritems() to python3 dict.items(). iteritems was removed in python3 meaning these script will otherwise not run. Note that this remains backwards compatible since dict.items() also existed in python2, though the implementation was more memory intensive for large dicts (which these likely aren't). This is similar to https://dart-review.googlesource.com/c/sdk/+/200184 Change-Id: I4fe5c90d21de97d0ecceb27fa6efa7d7deb14098 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/200864 Reviewed-by: Alexander Thomas <athom@google.com> Commit-Queue: Clement Skau <cskau@google.com>
