一、单数与复数 1.find_element开头的是13种单数定位 2.find_elements开头是13种复数定位 二、 定位一组对象 1.对比用单数定位find_element和复数定位find_elements定位元素的结果 ``` # coding:utf-8 from appium import webdriver desired_caps = { 'platformName': 'Android', 'deviceName': '127.0.0.1:62...
之前学过元素的8中定位方式,都是find_element_by_定位方法,定位的元素返回都是一个值,定位的方法同样适用于find_elemnts,不同的是:这种定位方式返回的值是一个list列表,可以通过索引值的方式,输出具体的元素。书写方式find_elements_by_定位方法。 二、练习内容及目标 1.练习的内容 百度搜索框中输入要搜索的值,...

Theindex()method is used to find the index of the first occurrence of a specified element in a list. This method is particularly useful when you need to know the position of a specific element within a list. Here’s an example of how to use theindex()method to find the index of the...
在Python爬虫中,我们常常使用Selenium来获取动态页面内容。在使用Selenium时,定位页面元素是非常关键的一步。下面,我们将介绍Selenium的8种find_element元素定位方式,并附上实际案例。 id定位通过元素的id属性来定位元素。这是最直接、最准确的定位方式。示例代码: driver.find_element_by_id('element_id') Name定位...
