將列表列表寫入 csv 並在 python 中出現 UnicodeEncodeError

Question

我正在使用 openpyxl 庫將 xlsm 文件轉換為 csv。 我遇到的問題是，當我嘗試將列表列表傳遞給 csv python 時返回以下錯誤：

回溯（最后一次調用）：文件“test.py”，第 21 行，在 listIntoCsv(finalList) 文件“test.py”，第 16 行，在 listIntoCsv write.writerows(list) UnicodeEncodeError: 'ascii' codec can't在 position 20 中編碼字符 u'\xfa'：序數不在范圍內（128）

這些是最終列表中 1 個列表的 2 個示例：

[[u'0@mediador.jordilazo.com', u'SZHK@jordilazo.es, NFUW@competencia.es', datetime.datetime(2022, 7, 18, 10, 7, 16), 1L, '0', 1L, 2L, 'NO', None, 'SZHK@competencia.es', 'NFUW@competencia.es', None, None, False, False, None, None, False, False, False, None, None, True, 'SI', 'N/A', 3182L, 0L, None, None, None, '#N/A', 'RE: NHYJIJJP< >LWWM', u'a7d2a497-e4f1-40b2-8dc8-699b270bbcd4', u'Comentario: \xd1<GRC?SST"&"\\ A', None], [u'MMUN19@jordilazo.com', u'SYPV@jordilazo.es, IFMT@competencia.es', datetime.datetime(2022, 7, 18, 9, 3, 49), 1L, 'MMUN19', 1L, 2L, 'NO', None, 'SYPV@competencia.es', 'IFMT@competencia.es', None, None, False, False, None, None, False, False, False, None, None, True, 'SI', 'N/A', 'SI', 'N/A', None, None, None, 'DGT Madrid', 'RE: NIPGGVJK< >FJRQ', u'2cd7a6f2-4ce4-4678-b592-bff465f9f411', u'Comentario: \xd1@GHJ<FCX"&"\\ A', None]]

我正在用 python2 執行代碼。 我嘗試應用不同的解決方案，使代碼如下所示：

from openpyxl import load_workbook
import csv
import codec

  excelFile = load_workbook('test.xlsm', data_only=True)
  currentSheet = excelFile.worksheets[0]
  
  def iter_rows(currentSheet):
    for row in currentSheet.iter_rows():
      yield [cell.value for cell in row]

  def listIntoCsv(list):
    with codecs.open('test','w',encoding='UTF-8') as f:
      write = csv.writer(f)
      write.writerows(list)
  
  finalList = list(iter_rows(currentSheet))
  print(finalList)
  listIntoCsv(finalList)
