我知道已經存在這個問題的變體，并且我已經完成了它們。具體來說，我遇到的問題是here和here。我已經嘗試使用列出的所有解決方案，但它確實對我不起作用，因為在我的情況下，我必須遍歷另一個字典，而且很多時候 dict 的 dict 中的鍵也將是相同的（在這種情況下值應該變成一個列表。讓我用一個例子來說明：可以說entity_sentiment_dictionary是我要附加到的字典 fromentity_sentiment_int_int_dictentity_sentiment_dictionary = { 'name': {'userid1': 0.0}, 'Aditya': {'userid1': 0.0}, 'Glen': {'5dad13fc54aeb500078637e0': -0.10000000149011612}, 'Kenta': {'5dad13fc54aeb500078637e0': 0.0}, 'Keita': {'5dd23a18c7949300087d8d88': 0.0}, 'Ganchan': {'5dd23a18c7949300087d8d88': 0.0}, 'Anna': {'5dd23a18c7949300087d8d88': 0.0}, 'Joe': {'5dd23a18c7949300087d8d88': 0.8999999761581421}}entity_sentiment_int_int_dict = { 'name': {'userid1': 0.1}, 'Aditya': {'userid2': 0.3}}當我更新時，結果應該是這樣的：entity_sentiment_dictionary = { 'name': {'userid1': [0.0,0.1]}, 'Aditya': {'userid1': 0.0, 'userid2': 0.3}, 'Glen': {'5dad13fc54aeb500078637e0': -0.10000000149011612}, 'Kenta': {'5dad13fc54aeb500078637e0': 0.0}, 'Keita': {'5dd23a18c7949300087d8d88': 0.0}, 'Ganchan': {'5dd23a18c7949300087d8d88': 0.0}, 'Anna': {'5dd23a18c7949300087d8d88': 0.0}, 'Joe': {'5dd23a18c7949300087d8d88': 0.8999999761581421}}這是我在嘗試了我可以在網上找到的所有方法后所達到的目標：for key in entity_sentiment_int_int_dict.keys(): if key in entity_sentiment_dictionary: for k in entity_sentiment_dictionary.keys(): if key==k: entity_sentiment_dictionary[key][k] = dict(entity_sentiment_int_int_dict[key]) else: entity_sentiment_dictionary[key] = entity_sentiment_int_int_dict[key]我覺得我快到了，需要對嵌套的 for 循環進行更改。感謝您提供任何幫助，并且還建議使用任何其他方式來獲得預期結果。

這是一個解決方案：
for k, v in entity_sentiment_int_int_dict.items():
if k in entity_sentiment_dictionary.keys():
entry = entity_sentiment_dictionary[k]
for update_key, update_val in v.items():
if update_key in entry:
if isinstance(entry[update_key], list):
entry[update_key].append(update_val)
else:
entry[update_key] = [entry[update_key], update_val]
else:
entry[update_key] = update_val
# with 'out' as desired output dict from OP:
entity_sentiment_dictionary == out # True
完整的代碼重現：
entity_sentiment_dictionary = { 'name': {'userid1': 0.0},
'Aditya': {'userid1': 0.0},
'Glen': {'5dad13fc54aeb500078637e0': -0.10000000149011612},

'Joe': {'5dd23a18c7949300087d8d88': 0.8999999761581421}}
entity_sentiment_int_int_dict = { 'name': {'userid1': 0.1},
'Aditya': {'userid2': 0.3}}
out = {'name': {'userid1': [0.0,0.1]},
'Aditya': {'userid1': 0.0, 'userid2': 0.3},

'Anna': {'5dd23a18c7949300087d8d88': 0.0},
'Joe': {'5dd23a18c7949300087d8d88': 0.8999999761581421}}
for k, v in entity_sentiment_int_int_dict.items():
if k in entity_sentiment_dictionary.keys():
entry = entity_sentiment_dictionary[k]
for update_key, update_val in v.items():
if update_key in entry:
if isinstance(entry[update_key], list):
entry[update_key].append(update_val)
else:
entry[update_key] = [entry[update_key], update_val]
else:
entry[update_key] = update_val
斷言測試和實際輸出：
print(f"Result matches desired output: {entity_sentiment_dictionary == out}")
# Result matches desired output: True
entity_sentiment_dictionary

這可以滿足您的要求?？梢赃M一步優化。
for key in entity_sentiment_int_int_dict.keys(): if key in entity_sentiment_dictionary.keys(): if entity_sentiment_dictionary[key].keys() == entity_sentiment_int_int_dict[key].keys(): temp = [] temp.append(next(iter(entity_sentiment_dictionary[key].values()))) temp.append(next(iter(entity_sentiment_int_int_dict[key].values()))) entity_sentiment_dictionary[key][next(iter(entity_sentiment_dictionary[key].keys()))] = temp else: entity_sentiment_dictionary[key].update(entity_sentiment_int_int_dict[key]) else: entity_sentiment_dictionary.update(entity_sentiment_int_int_dict[key])
