python向已存在的excel中新增表,不覆盖原数据 python向已存在的excel中新增表,不覆盖原数据的实例

import xlwt
import xlrd
from xlutils.copy import copy
#打开需要操作的excel表
wb=xlrd.open_workbook(path)
#复制原有表
newb=copy(wb)
#新增sheet,参数是该sheet的名字，可自定义
wbsheet=newb.add_sheet(dl+'-'+dn)
#向新sheet中写入数据。本代码中的d是某个dataframe
wbsheet.write(0,0,'date')
wbsheet.write(0,1,'visited')
wbsheet.write(0,2,'success')
for i in range(d.shape[0]):
  wbsheet.write(i + 1, 0, d.iloc[i, 0])
  for j in range(1,d.shape[1]):
    wbsheet.write(i+1,j,int(d.iloc[i,j]))
#获取原有excel表中sheet名为‘summary'的sheet
sumsheet=newb.get_sheet('summary')
#k表示该sheet的最后一行
k=len(sumsheet.rows)
#想原有sheet后面新增数据
sumsheet.write(k,0,dl+'-'+dn)
sumsheet.write(k,1,int(sum(d['visited'])))
sumsheet.write(k,2,int(sum(d['success'])))
#保存为原有的excel表路径
newb.save(path)
