python实现xlwt xlrd 指定条件给excel行添加颜色

import xlwt
import xlrd
from xlutils.copy import copy
#创建execl
def create_execl(file_name):
 wb = xlwt.Workbook()
 ws = wb.add_sheet('Info')
 ws.write(0, 0, "1")
 ws.write(1, 0, "2")
 ws.write(2, 0, "3")
 ws.write(3, 0, "2")
 wb.save(file_name)
#单元格上色
def color_execl(file_name):
 styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour red;') # 红色
 rb = xlrd.open_workbook(file_name)  #打开t.xls文件
 ro = rb.sheets()[0]      #读取表单0
 wb = copy(rb)       #利用xlutils.copy下的copy函数复制
 ws = wb.get_sheet(0)     #获取表单0
 col = 0         #指定修改的列
 for i in range(ro.nrows):    #循环所有的行
  result = int(ro.cell(i, col).value)
  if result == 2:      #判断是否等于2
   ws.write(i,col,ro.cell(i, col).value,styleBlueBkg)
 wb.save(file_name)
 
if __name__ == '__main__':
 file_name = 't.xls'
 create_execl(file_name)
 color_execl(file_name)
