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...

Theheadersargument passed to thestart_responsecallback must be a Pythonlistoftuples, with each tuple composed as(header_name, header_value). Both the name and value of each header must be strings (regardless of Python version). This is a rare example in which type matters, as this is ind...
print(fruits[0]) #index 0 is the first element print(fruits[1])print(fruits[2])Output:Apple Banana Orange 但是，索引不必总是为正。如果想逆向访问列表，也就是按照相反的顺序，可以使用负索引，如下所示：#Access elements in the fruits list using negative indexesfruits = ['Apple','Banana', "...
