你可以使用内置的


csv


要在您的XLSX文件旁边写入CSV的模块，您只需要以不同的方式创建它：

    
      import csv
import io
import xslxwriter
xlsx_data = io.BytesIO()
csv_data = io.StringIO()  # on Python 2.x use io.BytesIO()
XLSX part
workbook = xlsxwriter.Workbook(xlsx_data, {‘in_memory’: True})
worksheet = workbook.add_worksheet()
CSV part
csv_writer = csv.writer(csv_data)
Some data we want to write to the worksheet.
expenses=([‘OriginalURL’, ‘NormalizedURL’, ‘Response’, ‘DuplicateOf’,
           ‘SourceId’, ‘RelatedSources’],)
for row, data in enumerate(expenses):
# XSLX part
worksheet.write_row(row, 0, data)  # if needed, add an offset to the row/column
# CSV part
csv_writer.writerow(row)
workbook.close()
CSV data available in csv_data, XLSX data available in xlsx_data
