Multiple indentation is not displayed

[pigletiger]

It would be nice if tasks with multiple parents (i.e., parents with parents) could be displayed with the correct indentation. I've implemented this using a nasty hack for up to three levels of indentation; it should be possible to make a recursive function to replace what I've written, which would allow any amount of indentation.

Here's my attempt, with each level of recursion manually written:

def tasks(listID):
    tasks = service.tasks().list(tasklist=listID).execute()
    try:
        for task in tasks['items']:
            if task['title'] == '': pass
            else:
                taskName=task['title']
                if 'parent' in task.keys():
                    for maybeParent in tasks['items']:
                        if maybeParent['title'] == '': pass
                        else:
                            if maybeParent['id'] == task['parent']:
                                if 'parent' in maybeParent.keys():
                                    for maybeParentsParent in tasks['items']:
                                        if maybeParentsParent['title'] == '': pass
                                        else:
                                            if maybeParentsParent['id'] == maybeParent['parent']:
                                                if 'parent' in maybeParentsParent.keys():
                                                    print '            '+'• '+task['title'].encode('utf-8')
                                                    break
                                                else:
                                                    print '        '+'• '+task['title'].encode('utf-8')
                                                    break
                                else:
                                    print '    '+'• '+task['title'].encode('utf-8')
                                    break
                else:
                    print '• '+task['title'].encode('utf-8')
    except KeyError: print '    No tasks.'
