 3 import os
 4 # 步骤1：获取excel文件的绝对路径
 5 dirPath = os.path.join(os.getcwd(),"data")
 6 if not os.path.exists(dirPath):
 7     os.mkdir(dirPath)
 8 
 9 excelPath = os.path.join(dirPath,"data.xls")

19 for colsIndex in range(len(headers)):
20     worksheet.write(0,colsIndex,headers[colsIndex])
21 
22 #步骤4-3：循环写入其他表格内容
23 for rowIndex in range(1,4):
24     for colsIndex in range(len(headers)):
25         worksheet.write(rowIndex,colsIndex,(rowIndex+colsIndex))
