本章题要:
本章节主要是封装底层操作类,将页面操作都封装到一个操作中,并结合我们之前的element_excel_utils中的部分信息结合使用
- 实现demo
demo_base_page_23.py

在此我们先了解一下匿名函数的用法,匿名函数有哪些优点?
- 不用取名称,因为给函数取名是比较头疼的一件事,特别是函数比较多的时候
- 可以直接在使用的地方定义,如果需要修改,直接找到修改即可,方便以后代码的维护工作
- 语法结构简单,不用使用def 函数名(参数名):这种方式定义,直接使用lambda 参数:返回值 定义即可
举例:比方说,我要写一个函数用于两个数相乘

- 在common文件夹下新建base_page.py 将写好的代码copy进去

基本上的封装方式就是这样的,大家可以自己根据项目的情况封装一些使用的方法
