python实现持久化存储，操作表格，时间戳

 import xlrd,xlwt,pickle,time,datetime
 book = xlrd.open_workbook("练习.xlsx")
 sheet1 = book.sheet_by_index(0)
 rownum=sheet1.nrows
 data=[]
 for i in range(4, rownum):
     if i >= 76:
         cls={}
         cls['name']=sheet1.cell_value(i,0).strip()
         data.append(cls)
     elif(i-1)%3==0:
         cls = {}
         name=sheet1.cell_value(i,0).strip()#班级
         cls['teacher'] = sheet1.cell_value(i + 1, 2).strip()
         cls['con']=[i for  i in sheet1.row_values(i)[2:] if i!='']
         cls['room'] = sheet1.cell_value(i + 2, 2).strip()
         cls['name']=name
         data.append(cls)
 print(data)

 with open('data0.txt','wb') as f:
     pickle.dump(data,f)

 wb = xlwt.Workbook(encoding='utf-8')
 ws = wb.add_sheet('A Test Sheet')

 for i in range(0,24):
     ws.write(i,0,data[i]['name'])
     ws.write(i,1,data[i]['teacher'])
     ws.write(i,2,data[i]['room'])
     ws.write(i,3,data[i]['con'])

 for j in range(24,38):
     ws.write(j, 0, data[j]['name'])

 s = time.time()
 Time = time.localtime(s)
 # print(Time)
 Tme = time.strftime("%Y%m%d%H%M%S", Time)
 print(Tme)
 now = datetime.datetime.now()
 print(now)
 # print(ss)
 wb.save(str(Tme)+'.xls')

s = time.time()是获取时间元年，为了测试用，可省略
Time = time.localtime(s)是获取本地时间，为元组形式

Tme = time.strftime("%Y%m%d%H%M%S", Time)将元组转换为时间戳

wb.save(str(Tme)+'.xls')只能用字符串拼接，并且Tme中不能有:.
