问题 I have the below HTML element that I need to find. Now, this "id" name is dynamic in the way that the int "0" at the end will change, but I know what it will be. The first int in "0-0" will also change, but it doesn't matter what it will be. <div id="ui-select-choices-row-0-0"> I've tried the below code that looks for an element that starts with "#ui-select-choices-row-" and ends with the desired input of "int", but it's not finding it as expected. Any suggestions on what I'm doing wrong here

web端自动化——Selenium3+python自动化（3.7版本）-chrome67环境搭建

阅读更多关于 web端自动化——Selenium3+python自动化（3.7版本）-chrome67环境搭建

前言目前selenium版本已经升级到3.0了，网上的大部分教程是基于2.0写的，所以在学习前先要弄清楚版本号，这点非常重要。本系列依然以selenium3为基础。一、selenium简介 Selenium 是用于测试 Web 应用程序用户界面 (UI) 的常用框架。它是一款用于运行端到端功能测试的超强工具。您可以使用多个编程语言编写测试，并且 Selenium 能够在一个或多个浏览器中执行这些测试。 Selenium的发展经历了三个阶段，第一个阶段，也就是selenium1的时代，在运行selenium1.0程序之前，我们得先启动selenium server 端(selenium remote control)，我们简称RC。RC主要包括三个部分：launcher，http proxy，selenium core。其中selenium core是被selenium server嵌入到浏览器页面中的，selenium core内部是一堆javascript函数构成，通过调用这些函数来实现对浏览器的各种操作。很显然比较繁琐，这并不是最佳自动化解决方案，于是后来有了webdriver。 selenium2 的时代合并了webdriver，也就是我们通常说的selenium，selenium2是默认支持Firefox浏览器的，这点非常方便。当然也支持其他更多浏览器

练习抓取淘宝商品信息

阅读更多关于练习抓取淘宝商品信息

##准备查看淘宝的页面是不是静态页面，结果是静态页面。想要抓取的是淘宝搜索某个商品的信息，所以要找到淘宝的搜索接口，经过观察可以看到接口可以这样解决： word = '书包' url = 'https://s.taobao.com/search?q=' + word 其实抓取淘宝主要是想加强自己对正则表达式的理解与运用的，于是决定用requests+re来完成此次练习。 ##调试 ####抓取网页调试的第一步获取网页的源代码就遇到了问题，真是不幸。于是开始痛苦的调试过程：在头部信息中添加浏览器信息结果：失败在头部信息中添加referer 结果：失败在头部信息中添加cookie 结果：返回结果有了变化，于是很高兴的去把requests发起的请求改成session会话发起的请求，结果最后发现虽然和以前返回的内容变了，但源代码还是错误的，简直崩溃，不知道用了什么反爬虫技术。终极武器----selenium 用这个直接调用真实的浏览器对其访问，终于不会出错了（这还是要出错，真的是无fuck可说了），但这个要启动浏览器，速度可能会很慢，所以我把源代码保存到了本地，避免重复访问浪费时间。保存网页保存的话用二进制的形式保存，不会出现一些乱七八糟的编码错误，而且用浏览器打开的时候可以显示中文，但用Python读取的时候，显示不出来中文，需要解码才能显示中文

问题 Using python, chromedriver and Windows. I've working on a script for some months which uses .click() function regularly, few days ago it stopped working anywhere on the site.
