dict2 = {'key1': 'aa', 'key2': 'ab', 'key3': 'ac', 'key4': 'ad', 'key5': 'ae', 'key6': 'af', 'key7': 'ag', 'key8': 'ah', 'key9': 'ai', 'key10': 'aj', 'key11': 'ak', 'key12': 'al', 'key13': 'am', 'key14': 'an', 'key15': 'ao', 'key16': 'ap', 'key17': 'aq', 'key18': 'ar', 'key2': 'as', 'key19': 'at', 'key20': 'au', 'key21': 'av', 'key22': 'aw', 'key23': 'ax', 'key24': 'ay', 'key25': 'az'}
dict3应将dict1的所有键替换为dict2的键，其中dict1的键= dict2的值。
预期输出为：
dict3 = {'key18': {'key25': {'key10': {'key23': 'qua-la-sa',
'key9': {'key13': 'masan.com',
'key15': 'swan toro',
'key24': 'ryan'}},
'key16': {'key11': 'stepg-sdd:sdf', 'key20': 'asfd.asf'},
'key19': 'pirat9333',
'key21': {'key3': {'key1': 'http://swan.com',
'key13': '1123',
'key8': 'ryan'},
'key6': 'Tran swa'},
'key22': {'key17': '1234bfh',
'key9': {'key17': 'ejs-33',
'key2': {'key2': '213bvn',
'key24': 'qwqwa-wnnf'},
'key24': 'mnhfg'}},
'key5': {'key17': 'talo',
'key9': {'key13': 'yo',
'key17': 'go',
'key2': {'key12': 'kato',
'key17': 'so',
'key2': 'mo',
'key24': 'to'},
'key24': 'wed'}}},
'key4': 'tues',
'key7': 'mon'}}
因为它是一个高度嵌套的字典，我无法获得预期的输出。
答案 0 :(得分：1)
反转dict2，以便您可以将dict1中的键直接映射到新键：
dict2_inverse = {v: k for k, v in dict2.items()}
然后通过重新映射密钥的其他字典递归：
def recursive_remap(d, keymap):
if isinstance(d, dict):
return {keymap[k]: recursive_remap(v, keymap) for k, v in d.items()}
return d
dict3 = recursive_remap(dict1, dict2_inverse)
演示：
>>> from pprint import pprint
>>> def recursive_remap(d, keymap):
... if isinstance(d, dict):
... return {keymap[k]: recursive_remap(v, keymap) for k, v in d.items()}
... return d
...
>>> dict1 = {'ar': {'az': {'ae': {'aq': 'talo', 'ai': {'aq': 'go', 'ay': 'wed', 'as': {'aq': 'so', 'ay': 'to', 'as': 'mo', 'al': 'kato'}, 'am': 'yo'}}, 'aj': {'ai': {'ay': 'ryan', 'am': 'masan.com', 'ao': 'swan toro'}, 'ax': 'qua-la-sa'}, 'ap': {'ak': 'stepg-sdd:sdf', 'au': 'asfd.asf'}, 'at': 'pirat9333', 'aw': {'aq': '1234bfh', 'ai': {'aq': 'ejs-33', 'ay': 'mnhfg', 'as': {'ay': 'qwqwa-wnnf', 'as': '213bvn'}}}, 'av': {'ac': {'aa': 'http://swan.com', 'ah': 'ryan', 'am': '1123'}, 'af': 'Tran swa'}}, 'ad': 'tues', 'ag': 'mon'}}
