+1 For getting change_type also set on diff item when create_patch=True.

@SongXueZhi Approach depends on your intention for further processing, but you can certainly retrieve the change type info even from a Diff generated with create_patch=True:
\n
def get_change_type_of_diff_item(diff_item):\n    if diff_item.new_file:\n        change_type = 'Added'\n    elif diff_item.deleted_file:\n        change_type = 'Deleted'\n    elif diff_item.renamed_file:\n        change_type = 'Renamed'\n    elif diff_item.copied_file:\n        change_type = 'Copied'\n    else:\n        change_type = 'Modified'\n    return change_type\n
\n
Usage Example:
\n
repo = git.Repo('/path/to/repository')\ndiff_index = repo.head.commit.diff(None, create_patch=True)\nfor diff in diff_index:\n    print(f\"{get_change_type_of_diff_item(diff)}: {diff.a_path if diff.a_path else diff.b_path}\")\n```\n
