我正在使用Python中的Selenium WebDriver編寫簡單的測試自動化腳本,但問題與Python相關,而與Selenium無關。 有兩個類FindByXPATH_1(base)& FindByXPATH_2(派生)。我想用FindByXPATH_2的方法在基類中調用屬性「driver」,但是當我運行代碼時,出現AttributeError:「type object'FindByXPATH_1''沒有屬性'driver'」Python中的類:AttributeError
這是代碼:「AttributeError錯誤:類型的對象‘FindByXPATH_1’有沒有屬性‘司機’」
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()
運行代碼我得到一個消息後 我怎麼能稱之爲屬性?
