    getphone = driver.find_element_by_class_name('_3ko75')[-1]

Answer 1

根据你的代码试验，得到最后的标题WebElement based on the value of the classname attribute you can use either of the following Locator Strategies：

使用 XPATH、find_element* 和 last():

print(driver.find_element_by_xpath("//*[@class='_3ko75'][last()]").get_attribute("title"))

使用 XPATH、find_elements* 和 [-1]:

print(driver.find_elements_by_xpath("//*[@class='_3ko75']")[-1].get_attribute("title"))

最好使用WebDriverWait:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//*[@class='_3ko75'][last()]"))).get_attribute("title"))

或

print(WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='_3ko75']")))[-1].get_attribute("title"))
