我有一张银行对账单，并已使用 Regex 提取表中的所有项目。名单是

我需要以这种格式存储它们：

Date        Item                           Name         Amount    Total

列表中的每一行

【解决方案1】：

在列表中使用命名元组“事务”，您可以收集所有数据，尽管项目和名称仍需要更清晰的正则表达式分离：

from collections import namedtuple
import re

l = [
    "15-10-2019 BIL/INFT/001823982708/Block2B5/ MAHAK JUNEJA 5,130.00 5,19,319.08",

    "30-10-2019 107510010791I0 Int on FD/RD XXX0791 Tds:0.Int:8625 and TAX:0. 8,625.00 4,72,973.08",
    "31-10-2019 CHEQUE 7055 CLG/ADVANCE ENGINEERING CORPORATION/HSB 14,337.00 4,58,636.08",
]

cols = ["Date", "Item_Name", "Amount", "Total"]

date_pattern = re.compile(r"\d{2}-\d{2}-\d{4}", re.I)
item_and_name_pattern = re.compile(r"(?<=\d{2}-\d{2}-\d{4}\s).*", re.I)
amount_pattern = re.compile(r"\d+,\d+.\d+", re.I)
total_pattern = re.compile(r"\d+,\d+,\d+.\d+$", re.I)

Transaction = namedtuple("Transaction", cols)
transactions = []

for item in l:
    date = re.search(date_pattern, item).group()
    total = re.search(total_pattern, item).group()
    temp_1 = item.rstrip(total)
    amount = re.search(amount_pattern, temp_1).group()
    temp_2 = temp_1.strip().rstrip(amount)
    item_and_name = re.search(item_and_name_pattern, temp_2).group()

    t = Transaction(date, item_and_name, amount, total)
    transactions.append(t)

for t in transactions:
    print(t)

Transaction(Date='15-10-2019', Item_Name='BIL/INFT/001823982708/Block2B5/ MAHAK JUNEJA ', Amount='5,130.00', Total='5,19,319.08')

【讨论】：

谢谢古斯塔夫！！我知道了解如何剥离项目和名称可能需要一点研究。这很好用。我需要插入一个 try catch 块来逃避数量不存在的错误。知道如何以字典格式表示结果吗？抱歉，我没有足够的声望来投赞成票。
out = [{k:v for k, v in f._asdict().items()} for f in transactions] 似乎起到了字典的作用
哇，看起来不错！很抱歉反馈迟了

我不确定您想如何存储这些值，但您可以使用以下拆分方法，
