import types

allGuests = {'Alice': {'apples': 5, 'pretzels': {'12':{'beijing':456}}},

             'Bob': {'ham sandwiches': 3, 'apple': 2},

             'Carol': {'cups': 3, 'apple pies': 1}}

def dictget(dict1,obj,default=None):

    for k,v in dict1.items():

        if k == obj:

            print(v)

        else:

            if type(v) is dict:

                re=dictget(v,obj)

                if re is not default:

                    print(re)

dictget(allGuests,'beijing')
