python--操作Excel

import xlwt
#写入Excel：

book = xlwt.Workbook()  #新建一个excel
sheet = book.add_sheet('sheet1')  #添加一个sheet页
sheet.write(0,0,'姓名')
sheet.write(0,1,'性别')
sheet.write(0,2,'年龄')
book.save('stu.xls') #微软的office不能用xlsx结尾的，wps随意

stus = [
      ['姓名','年龄','性别','分数'],
       ['mary', 20, '女', 89.9],
      ['mary', 20, '女', 89.9],
      ['mary', 20, '女', 89.9],
      ['mary', 20, '女', 89.9]
]
book = xlwt.Workbook()  #新建一个excel
sheet = book.add_sheet('sheet1')  #添加一个sheet页
raw = 0#控制行的
for stu in stus:
   col = 0 #控制列
   for s in stu:
      sheet.write(raw,col,s)
      col+=1
   raw+=1

book.save('kkk.xls')

#读取Excel：

import xlrd
book = xlrd.open_workbook('stu.xls') #打开一个excel
sheet = book.sheet_by_index(0) #根据顺序获取sheet
# sheet2 = book.sheet_by_name('sheet1') #根据sheet页名字获取sheet
# print(sheet.cell(0,0).value)  #指定行和列获取数据
# print(sheet.ncols) #获取excel里面有多少列
# print(sheet.nrows) #获取excel里面有多少行
sheet.row_values(1)#取第几行的数据
print(sheet.col_values(1)) #取第几列的数据
for i in range(sheet.nrows): # 0 1 2 3 4 5
   print(sheet.row_values(i)) #取第几行的数据

#修改Excel：

from xlutils.copy import copy
import xlrd
book1 = xlrd.open_workbook('stu.xls')
book2 = copy(book1)  #拷贝一份原来的excel
sheet = book2.get_sheet(0) #获取第几个sheet页
sheet.write(1,3,0)
sheet.write(1,0,'小黑')
book2.save('stu.xls')
