Help on method diff in module git.diff:

diff(other: Union[Type[git.diff.Diffable.Index], Type[ForwardRef('Tree')], object, NoneType, str] = <class 'git.diff.Diffable.Index'>, paths: Union[str, List[str], Tuple[str, ...], NoneType] = None, create_patch: bool = False, **kwargs: Any) -> 'DiffIndex' method of git.objects.commit.Commit instance
    Creates diffs between two items being trees, trees and index or an
    index and the working tree. It will detect renames automatically.
    
    :param other:
        Is the item to compare us with.
        If None, we will be compared to the working tree.
        If Treeish, it will be compared against the respective tree
        If Index ( type ), it will be compared against the index.
        If git.NULL_TREE, it will compare against the empty tree.
        It defaults to Index to assure the method will not by-default fail
        on bare repositories.
    
    :param paths:
        is a list of paths or a single path to limit the diff to.
        It will only include at least one of the given path or paths.
    
    :param create_patch:
        If True, the returned Diff contains a detailed patch that if applied
        makes the self to other. Patches are somewhat costly as blobs have to be read
        and diffed.
    
    :param kwargs:
        Additional arguments passed to git-diff, such as
        R=True to swap both sides of the diff.
    
    :return: git.DiffIndex
    
    :note:
        On a bare repository, 'other' needs to be provided as Index or as
        as Tree/Commit, or a git command error will occur
