如何使用python根據串列中的一些關鍵元素拆分資料？

以下是我回傳的串列

['aaa', 'bbb', 'ccc', 'ABN', 'AMRO', 'Bank', 'N.V.', '\nYour', 'monthly', 'statement', 'is', 'available', 'under', 'Self', 'service', '>', '\nDownload', 'statements', 'or', 'u', 'receive', 'them', 'by', 'mail.', 'aaa', 'bbb', 'ccc', 'ddd', '/TRTP/SEPA', 'OVERBOEKING/IBAN/NL93RABO0127299726/BIC/RABONL2U/NAME/', '\nPointbar', 'B.V./REMI/INV', '121-10005/EREF/NONREF', 'aaa', 'bbb', 'ccc', 'Settlement', 'FX/MM', '\nTrans.', 'Ref.', '0035979579', 'Deal', 'Ticket', 'ID', '6225447']

'ccc'如果元素 ' ddd' 不存在或從它開始'ddd'直到下一個元素，我想加入元素在元素之后開始'aaa'，我可以通過它獲得以下字串。

Settlement FX/MM

Deal Ticket ID 6225447

有人可以幫我嗎？嘗試此操作時，我陷入了嵌套的 for 回圈中。謝謝！

您可以用換行符替換aaa, bbb, ccc和ddd，然后拆分為多個換行符：

import re
data = ['aaa', 'bbb', 'ccc', 'ABN', 'AMRO', 'Bank', 'N.V.', '\nYour', 'monthly', 'statement', 'is', 'available', 'under', 'Self', 'service', '>', '\nDownload', 'statements', 'or', 'u', 'receive', 'them', 'by', 'mail.', 'aaa', 'bbb', 'ccc', 'ddd', '/TRTP/SEPA', 'OVERBOEKING/IBAN/NL93RABO0127299726/BIC/RABONL2U/NAME/', '\nPointbar', 'B.V./REMI/INV', '121-10005/EREF/NONREF', 'aaa', 'bbb', 'ccc', 'Settlement', 'FX/MM', '\nTrans.', 'Ref.', '0035979579', 'Deal', 'Ticket', 'ID', '6225447']
data = [' ' if i in ['aaa', 'bbb', 'ccc', 'ddd'] else i for i in data]
data = ' '.join([i for i in data]).strip()
data = re.split('\s\s\s ', data)

這將為您提供所需組的串列

print('\n\n'.join(data))：

你可以試試這個：

L = ['aaa', 'bbb', 'ccc', 'ABN', 'AMRO', 'Bank', 'N.V.', '\nYour', 'monthly', 'statement', 'is', 'available', 'under', 'Self', 'service', '>', '\nDownload', 'statements', 'or', 'u', 'receive', 'them', 'by', 'mail.', 'aaa', 'bbb', 'ccc', 'ddd',
     '/TRTP/SEPA', 'OVERBOEKING/IBAN/NL93RABO0127299726/BIC/RABONL2U/NAME/', '\nPointbar', 'B.V./REMI/INV', '121-10005/EREF/NONREF', 'aaa', 'bbb', 'ccc', 'Settlement', 'FX/MM', '\nTrans.', 'Ref.', '0035979579', 'Deal', 'Ticket', 'ID', '6225447']
i = 0
S = None
while True:
    try:
        _L = L[i:]
        o = _L.index('ccc')   1
        if _L[o] == 'ddd':
            o  = 1
        S = []
        while _L[o] != 'aaa':
            S.append(_L[o])
            o  = 1
        print(' '.join(S))
        S = None
        i  = o
    except (IndexError, ValueError):
        if S:
            print(' '.join(S))
        break

您可以嘗試使用正則運算式如下：

import re

data = ['aaa', 'bbb', 'ccc', 'ABN', 'AMRO', 'Bank', 'N.V.', 
  '\nYour', 'monthly', 'statement', 'is', 'available', 'under', 
  'Self', 'service', '>', '\nDownload', 'statements', 'or', 'u',
  'receive', 'them', 'by', 'mail.', 'aaa', 'bbb', 'ccc', 'ddd',
  '/TRTP/SEPA', 'OVERBOEKING/IBAN/NL93RABO0127299726/BIC/RABONL2U/NAME/', 
  '\nPointbar', 'B.V./REMI/INV', '121-10005/EREF/NONREF', 'aaa', 'bbb', 
  'ccc', 'Settlement', 'FX/MM', '\nTrans.', 'Ref.', '0035979579', 'Deal', 
  'Ticket', 'ID', '6225447']

#flatten the list
one_line = ' '.join(data)

#substitue groups 'aaa bbb ccc' and 'aaa bbb ccc ddd' with newline chars
print(re.sub(r'(aaa bbb ccc) | (aaa bbb ccc ddd)', '\n\n', one_line).lstrip())

輸出：
