selenium中 基本方法定义，封装后直接调用，太方便了

# 导入timem模块的sleep
from time import sleep
#导入selenium里的expected_conditions，selenium包需要自己导入可网上下载
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.support.wait import WebDriverWait
#调用封装好的 获取时间戳的方法，自行百度
from SYS_Operation import sys_operation
