假設我有一個代表句子的列表，例如：sent = ['terras', 'ipsius', 'Azar', 'vocatas', 'Ta', 'Xellule', 'et', 'Ginen', 'Chagem', 'in', 'contrata', 'Deyr', 'Issafisaf']以及地名列表places = ['Ta Xellule', 'Ginen Chagem', 'Deyr Issafisaf']我最終會如何：[('O','terras'), ('O', 'ipsius'), ('O', 'Azar'), ('O', vocatas'), ('PLACE', 'Ta'), ('PLACE', 'Xellule'), ('O','et'), ('PLACE', 'Ginen'), ('PLACE', 'Chagem'), ('O','in'), ('O','contrata'), ('PLACE', 'Deyr'), ('PLACE', 'Issafisaf')]快速說明：例如，如果Ta必須僅在Xellule旁邊。如果在句子中的其他上下文中發現，則不應將其標記為PLACE ex：Ta Buni mar Ta Xellule ...，僅應標記第二個Ta。這是我的地點清單的一個示例： 'Ras il Huichile', 'Ras il Hued', 'Ta Richardu', 'Roma', 'Russilion', 'La Rukiha', 'Irrukiha ta il Bayada', 'Casalis Milleri', 'Ta Sabat', 'Casalis Zebug', 'Ta Zagra', 'Sagra in Ras il Hued', 'Ta Isalme'這是一個例句：terras ipsius Azar vocatas Ta Xellule et Ginen Chagem in contrata Deyr Issafisaf cum iuribus suis omnibus在這里，盡管它存在于Ras il Hued的Sagra中，但不應標記為位置

好的，我根據您的修改更新了答案：
from functools import reduce
sent = "terras ipsius Azar vocatas Ta Ta Zagra Ta Zagra Xellule et Ginen Chagem in contrata Deyr Issafisaf cum iuribus suis omnibus"
places = [ 'Ras il Huichile', 'Ras il Hued', 'Ta Richardu', 'Roma', 'Russilion', 'La Rukiha', 'Irrukiha ta il Bayada',
'Casalis Milleri', 'Ta Sabat', 'Casalis Zebug', 'Ta Zagra', 'Sagra in Ras il Hued', 'Ta Isalme', 'Ta Xellule', 'Ginen Chagem',
'Deyr Issafisaf']
places_map = {p:[('PLACE', l) for l in p.split()] for p in places}
def find_places(sent, places):
if len(places) is 0:
return [('O', l) for l in sent.split()]
place = places[0]
remaining_places = places[1:]
sent_splits = sent.split(place)
return reduce(lambda a,b:a+places_map[place]+b, [find_places(s, remaining_places) for s in sent_splits])
print(find_places(sent, places))
輸出為：
[('O', 'terras'), ('O', 'ipsius'), ('O', 'Azar'), ('O', 'vocatas'), ('O', 'Ta'), ('PLACE', 'Ta'), ('PLACE', 'Zagra'), ('PLACE', 'Ta'), ('PLACE', 'Zagra'), ('O', 'Xellule'), ('O', 'et'), ('PLACE', 'Ginen'), ('PLACE', 'Chagem'), ('O', 'in'), ('O', 'contrata'), ('PLACE', 'Deyr'), ('PLACE', 'Issafisaf'), ('O', 'cum'), ('O', 'iuribus'), ('O', 'suis'), ('O', 'omnibus')]
因此，我使用了一種遞歸方法來查找句子中的位置，以所需的格式對其進行更改，然后對句子的其余部分與其余位置進行遞歸處理，然后將它們最終合并在一起。

嘗試這樣的事情：
res = []
for x in sent:
for place in places:
if x in place:
# add 'PLACE' if it matches
res.append(('PLACE', x))
if ('PLACE', x) not in res:
# add '0' if we find nothing
res.append(('0', x))
print(res)

這是一個僅基于列表理解的建議，適用于理解愛好者：
sent = ['terras', 'ipsius', 'Azar', 'vocatas', 'Ta', 'Xellule', 'et', 'Ginen', 'Chagem', 'in', 'contrata', 'Deyr', 'Issafisaf']
places = ['Ta Xellule', 'Ginen Chagem', 'Deyr Issafisaf']
p = [i for place in places for i in place.split()]
result = [('PLACE',word) if word in p else ('O',word) for word in sent]
print(result)
# [('O', 'terras'), ('O', 'ipsius'), ('O', 'Azar'), ('O', 'vocatas'), ('PLACE', 'Ta'),
# ('PLACE', 'Xellule'), ('O', 'et'), ('PLACE', 'Ginen'), ('PLACE', 'Chagem'),
# ('O', 'in'), ('O', 'contrata'), ('PLACE', 'Deyr'), ('PLACE', 'Issafisaf')]
