我试图建立一个数据集的以下形式（与所有投标人ID在文本中）：
| 投标者标识符|分包商数量|项目|
| - ------|- ------|- ------|
| 一|五个|26、27、58、59，剥离（部分），15、66、67、60至65、68、69、47|
| 03|三个|第二十六、二十七、五十八、五十九、六十八、六十九、四十七条|
非常感谢@Andrej Keseley，下面的代码捕获了我们想要的数据集中的大部分内容。

但是它不能捕获不是以ITEMS开头的字符串（比如STRIPING (PARTIAL)）。我不确定我们是否可以在当前代码中只使用regex来实现这一点。也许拆分文本会有所帮助？我不确定，仍在尝试解决这个问题。
任何帮助或领导将不胜感激!非常感谢!

当然，我想这可能行得通：
在代码中只需将

items = re.findall(r"ITEMS? (.*)", group)

与

items = re.findall(r"\w {3,}(.*)", group)

然后对data.append做一些小改动
留给你们的是

data = []
for id_, group in re.findall(
    r"(?s)BIDDER ID\D+DESCRIPTION OF PORTION OF WORK SUBCONTRACTED\D+(\d+)(.*?)(?=BIDDER ID|-{5,}|\Z)",
    document,
):
    items = re.findall(r"\w {3,}(.*)", group)
    data.append(
        {
            "bidder-id": id_,
            "number_subcontractors": group.count('\n\n'),
            "items": ", ".join(
                i.replace(" AND", ",").replace("ITEMS ", "").replace("ITEM", "").strip() for i in items
            ),
        }
    )

df = pd.DataFrame(data)
print(df)

这随后导致投标人ID09的项目列看起来像：

60 THRU 65 (PARTIAL), 68 THRU 69 (PARTIAL), EROSION CONTROL (PARTIAL), 28 (PARTIAL), STRIPING (PARTIAL), TRAFFIC CONTROL (PARTIAL), 47 (PARTIAL)

将文档文本中的所有表格数据加载到数据框中（包括分包商的名称和地址）可能会很有趣，这样您就可以从中检索所需的内容。
然后可以使用panda的groupby方法提取摘要信息：

import pandas as pd
import re

def load(document):
    data = []
    # Identify lines of interest by specific column layout
    res = re.findall(r"^ (.{8})  (\S.{0,60}$|\S.{58})(?:  (\S.*$))?", document, re.M)
    for a, b, c in res:
        bidder = a.strip() or bidder
        if c: # new subcontractor
            data.append({
                "bidder-id": bidder, 
                "items": re.sub(r" AND|ITEM(S )?", ",", c).strip(" ,"),
                "name": b.strip(),
                "address": ""
            })
        else: # continuation with address
            data[-1]["address"] = (data[-1]["address"] + "\n").lstrip() + b.strip()
    return pd.DataFrame(data)

subcontractors = load(document)
summary = subcontractors.groupby("bidder-id").agg(
           {"items": ", ".join, "name": "count"}
          ).rename(columns={"name": "number_subcontractors"})

对于示例文档，summary Dataframe 将具有：
| 投标者标识符|项目|分包商数量|
| - ------|- ------|- ------|
| 一|26、27、58、59，剥离（部分），15、66、67、60至65（部分），68、69、47|五个|
| 03|第二十六、二十七、五十八、五十九、六十八、六十九、四十七条|三个|
| 09|60至65（部分）、68至69（部分）、侵 eclipse 控制（部分）、28（部分）、剥离（部分）、交通控制（部分）、47（部分）|七|
| 十个|26、27、58、59（部分）、60至65（部分）、68、69（部分）、28（部分）、47（部分）|五个|
仅供参考，subcontractors Dataframe 如下所示：
| 投标者标识符|项目|姓名|地址|
