获取当前时间

import datetime
now_time = datetime.datetime.now()
print(now_time.strftime('%Y-%m-%d %H:%M:%S'))

如果结合对文件修改的时候需要把获取到的时间放置文件名中可以通过只去格式化的部分值插入到新命名str中

import datetime
from xlrd import open_workbook
from xlutils.copy import copy
now_time = datetime.datetime.now()
now_time_year = now_time.strftime('%Y-%m-%d')
now_time_H = now_time.strftime('%H')
now_time_M = now_time.strftime('%M')
now_time_S = now_time.strftime('%S')
rb = open_workbook('D:\qiuwenbin.xlsx')
wb = copy(rb)
ws = wb.get_sheet(0)
ws.write(1,1,283)
wb.save('D:\qiuwenbin({},{}时{}分{}秒).xlsx'.format(now_time_year,now_time_H,now_time_M,now_time_S))
