Equivalent to git tag --contains <commit>

[bytefluxio]

What would be the gitpython equivalent of git tag --contains <commit>

I need to ascertain all tags that point to descendants of a commit. The git command is incredibly fast, but doing the following just isn't effective:

tags = []
  for tag in self.repo.tags:
      if self.repo.is_ancestor(git_hash, tag.commit):
          tags.append(tag)

I would go with self.repo.git.tag(contains=commit).
