我正在使用Python中的Selenium WebDriver编写简单的测试自动化脚本,但问题与Python相关,而与Selenium无关。 有两个类FindByXPATH_1(base)& FindByXPATH_2(派生)。我想用FindByXPATH_2的方法在基类中调用属性“driver”,但是当我运行代码时,出现AttributeError:“type object'FindByXPATH_1''没有属性'driver'”Python中的类:AttributeError
这是代码:“AttributeError错误:类型的对象‘FindByXPATH_1’有没有属性‘司机’”
class FindByXPATH_1():
def __init__(self):
self.driver_location = '/usr/local/bin/chromedriver'
self.driver = webdriver.Chrome(self.driver_location)
self.driver.get('https://letskodeit.teachable.com/p/practice')
from basics.xpath_1 import FindByXPATH_1
import basics #the classes are in two different python files
class FindByXpath_2(FindByXPATH_1):
def __init__(self):
FindByXPATH_1.__init__(self)
def find_by_starts_with(self):
starting_with = FindByXPATH_1.driver.find_elements(By. XPATH,
'//div[@class="view-school"]//h3[starts-with(@)class, "subtitle"]')
print(len(starting_with))
test = FindByXPATH_2()
test.find_by_starts_with()
运行代码我得到一个消息后 我怎么能称之为属性?
