text based game get item and finishing game

Question

Alright so, I am currently trying to create a text based game for a class and im having a few small issues. the first of which being the carrying value I've created doesn't want to pick up items and I also cannot figure out how to make the loop break in the final room. Im pretty new to this so im not 100% sure on how to ask but here's my code

import time

rooms = {
    'Great Hall': {'name': 'Great Hall', 'South': 'Dining Room', 'North': 'Armory',
                   'East': 'Hallway', 'West': 'Bedroom', 'text': 'The Great Hall, begin your quest'},

    'Bedroom': {'name': 'Bedroom', 'East': 'Great Hall', 'contents': 'Magic wand',
                'text': 'A Bedroom. There appears to be a Magic wand in the corner'},

    'Hallway': {'name': 'Hallway', 'West': 'Great Hall', 'North': 'Cellar', 'contents': 'Sword',
                'text': 'A Hallway. There appears to be a Sword on the wall'},

    'Cellar': {'name': 'Cellar', 'South': 'Hallway', 'contents': 'Book',
               'text': 'A Cellar. There is a Book on a shelf'},

    'Dining Room': {'name': 'Dining Room', 'North': 'Great Hall', 'East': 'Kitchen', 'contents': 'Potion',
                    'text': 'The Dining Room. It looks like somebody left their Potion behind...'},

    'Kitchen': {'name': 'Kitchen', 'West': 'Dining Room', 'contents': 'Shield',
                'text': 'A Kitchen. What a strange place to find a Shield'},

    'Armory': {'name': 'Armory', 'South': 'Great Hall', 'East': 'Proving Grounds', 'contents': 'Armor',
               'text': 'The Armory. That Armor looks like it would fit you...'},

    'Proving Grounds': {'name': 'Proving Grounds', 'contents': 'Minotaur',
                        'text': 'The Proving Grounds. Are you ready for your showdown?'}
}
directions = ['North', 'South', 'East', 'West']
currentRoom = rooms['Great Hall']
carrying = []

    # print a main menu and the commands

        else:
