Solve the following python programming problem given the following code:
@ classmethod 
def _create(cls, target_class, project = None, is_public = False, schema = None, data = None, archive = False, embargo = None, registration_approval = None, retraction = None, * args, **kwargs) : 
    save_kwargs (** kwargs) 
    user = None 
    if project : 
        user = project.creator 
user = (kwargs.get ('user') or kwargs.get ('creator') or archive or UserFactory ()) 
    kwargs ['creator'] = user 
    project = (project or target_class (* args, ** kwargs)) 
    if (user._id not in project.permissions) : 
        project.add_contributor (contributor = user, permissions = permissions.CREATOR_PERMISSIONS, log = False, save = False) 
project.save () 
    schema = (schema or get_default_metaschema ()) 
    data = (data or { 
        'some' : 'data', 
}) 
    auth = Auth (user = user) 
    register = (lambda : project.register_node (schema = schema, auth = auth, data = data)) 
    def add_approval_step(reg) : 
        if embargo : 
            reg.embargo = embargo 
else : 
            if registration_approval : 
                reg.registration_approval = registration_approval 
else : 
                if retraction : 
                    reg.retraction = retraction 
else : 
                    reg.require_approval (reg.creator) 
reg.save () 
        reg.sanction.add_authorizer (reg.creator, reg) 
        reg.sanction.save () 
if archive : 
        reg = register () 
        add_approval_step (reg) 
else : 
        with patch ('framework.celery_tasks.handlers.enqueue_task') : 
            reg = register () 
            add_approval_step (reg) 
with patch.object (reg.archive_job, 'archive_tree_finished', Mock (return_value = True)) : 
            reg.archive_job.status = ARCHIVER_SUCCESS 
            reg.archive_job.save () 
            reg.sanction.state = Sanction.APPROVED 
            reg.sanction.save () 
ArchiveJob (src_node = project, dst_node = reg, initiator = user) 
    if is_public : 
        reg.is_public = True 
reg.save () 
    return reg 

    
    

    Fix the buggy line: user = (kwargs.get ('user') or kwargs.get ('creator') or archive or UserFactory ())

#Here is Python program to fix the buggy line: user = (kwargs.
