我解析了一些txt文件并获得以下列表：
\nprice = [\'S-1\', \'20040319\', \'\\t\\t\\t\\tDIGIRAD CORP\', \'\\t\\t0000707388\', \'price to be between $and $per \', \'S-1\', \'20040408\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\', \'S-1\', \'20041027\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\', \'S-1\', \'20050630\', \'\\t\\t\\t\\tSEALY CORP\', \'\\t\\t0000748015\', \'S-1\', \'20140512\', \'\\t\\t\\t\\tCITIZENS FINANCIAL GROUP INC/RI\', \'\\t\\t0000759944\', \'initial public offering and no public market exists for our shares.

We are offering    shares of our common stock and the selling shareholder identified in this prospectus is offering    shares of our common stock. We will not receive any of the proceeds from the sale of shares by the selling shareholder. We anticipate that the initial public offering price of our common stock will be between $   and $   per \', \'S-1\', \'20020813\', \'\\t\\t\\t\\tVISTACARE INC\', \'\\t\\t0000787030\']\n我想要的输出是一个csvS-1文件，其中每一行都以每个“ ”文档（对应于不同的公司）开头。因此，我编写了第二个列表，该列表从 every 开始创建上述子列表\xe2\x80\x99S-1\xe2\x80\x99：
price2 = [s.strip(\'|\').split(\'|\') for s in re.split(r\'(?=S-1)\', \'|\'.join(price)) if s]\nprint(price2)\n[[\'S-1\', \'20040319\', \'\\t\\t\\t\\tDIGIRAD CORP\', \'\\t\\t0000707388\', \'price to be between $and $per \'], [\'S-1\', \'20040408\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\'], [\'S-1\', \'20041027\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\'], [\'S-1\', \'20050630\', \'\\t\\t\\t\\tSEALY CORP\', \'\\t\\t0000748015\'], [\'S-1\', \'20140512\', \'\\t\\t\\t\\tCITIZENS FINANCIAL GROUP INC/RI\', \'\\t\\t0000759944\', \'initial public offering and no public market exists for our shares. We anticipate that the initial public offering price will be between $and\'], [\'S-1\', \'20110523\', \'\\t\\t\\t\\tCeres, Inc.\', \'\\t\\t0000767884\', \' aggregate capital expenditures will be between $0.3 million\'], [\'S-1\', \'20171023\', \'\\t\\t\\t\\tBLUEGREEN VACATIONS CORP\', \'\\t\\t0000778946\', \' <div style="margin-top:14pt; text-align:justify; line-height:12pt;">This is the initial public offering of Bluegreen Vacations Corporation.

We anticipate that the initial public offering price of our common stock will be between $   and $   per \'], [\'S-1\', \'20020813\', \'\\t\\t\\t\\tVISTACARE INC\', \'\\t\\t0000787030\']]\n然后我在csv文件上写入：
\nwith open(\'pricerange.csv\', \'w\') as out_file:\n wr = csv.writer(out_file)\n wr.writerow(["file_form", "filedate", "coname", "cik", "price_range"]) # Headlines in top row\n wr.writerows(price2)\n输出看起来很好，每个子列表都被放置在一个新行中（即每行都以该\xe2\x80\x99S-1\xe2\x80\x99元素开头）。\n
为了进一步清理列表，我仍然想删除特殊字符（例如\' \'）。所以我创建了一个新price3列表：
price3 = re.sub(\'<.*?>|&([a-z0-9]+|#[0-9]{1,6}|#x[0-9a-f]{1,6});\', \'\', str(price2)) #remove special characters or html tags in original .txt files\nprint(price3)\n[[\'S-1\', \'20040319\', \'\\t\\t\\t\\tDIGIRAD CORP\', \'\\t\\t0000707388\', \'price to be between $and $per \'], [\'S-1\', \'20040408\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\'], [\'S-1\', \'20041027\', \'\\t\\t\\t\\tBUCYRUS INTERNATIONAL INC\', \'\\t\\t0000740761\'], [\'S-1\', \'20050630\', \'\\t\\t\\t\\tSEALY CORP\', \'\\t\\t0000748015\'], [\'S-1\', \'20140512\', \'\\t\\t\\t\\tCITIZENS FINANCIAL GROUP INC/RI\', \'\\t\\t0000759944\', \'initial public offering and no public market exists for our shares. We anticipate that the initial public offering price will be between $and\'], [\'S-1\', \'20110523\', \'\\t\\t\\t\\tCeres, Inc.\', \'\\t\\t0000767884\', \' aggregate capital expenditures will be between $0.3million\'], [\'S-1\', \'20171023\', \'\\t\\t\\t\\tBLUEGREEN VACATIONS CORP\', \'\\t\\t0000778946\', \' This is the initial public offering of Bluegreen Vacations Corporation.

有什么建议么？我看不出错误在哪里...\n非常感谢
\n没有错误，Excel 默认情况下使用 \' ;\' 而不是 \' ,\'，然后在您的示例中它将所有值 \xe2\x80\x8b\xe2\x80\x8bin 插入第一列。要正确查看 csv，您必须将 excel 设置分隔符从 \' \ ' 更改为;\' ,\' 或使用分隔符 \' ;\' 保存 csv 文件，如下所示：
with open(\'pricerange.csv\', \'w\') as out_file:\n wr = csv.writer(out_file, delimiter=";")\n wr.writerow(["file_form", "filedate", "coname", "cik", "price_range"]) # Headlines in top row\n wr.writerows(price2)\n
