使用 Selenium 将歌曲添加到 Spotify 播放列表的 Python 代码

Question

登录后，我的程序开始循环播放歌曲列表，以将它们添加到我的 Spotify 播放列表中。但是在第一个循环之后，它引发了“过时的元素引用：元素未附加到页面文档”异常。 Link I'm working on

driver=webdriver.Chrome()
driver.maximize_window()
actionChain = ActionChains(driver)
driver.get('https://open.spotify.com/browse/featured')
#Login Procedure
psw=''
login=driver.find_element_by_xpath("//button[2]").click()
sleep(1)
email=driver.find_element_by_id('login-username').send_keys('abc@yahoo.com')
password=driver.find_element_by_id('login-password').send_keys(psw)
login=driver.find_element_by_id('login-button').click() 

ignored_exceptions=(StaleElementReferenceException,NoSuchElementException)

def wdwfind(path):
    return WebDriverWait(driver, 15,ignored_exceptions=ignored_exceptions).until(
            EC.presence_of_element_located((By.XPATH,(path))))

def wdwclick(path):
    return WebDriverWait(driver, 15,ignored_exceptions=ignored_exceptions).until(
            EC.element_to_be_clickable((By.XPATH,(path))))


for n in range(len(songs)):
    wdwfind("//li[2]/div/a/div/span").click() #going to search tab
    wdwfind("//input").send_keys(songs[n]) #sending elements to navigation bar
    gotosong=wdwclick("//a[@class='d9eb38f5d59f5fabd8ed07639aa3ab77-scss _59c935afb8f0130a69a7b07e50bac04b-scss']") #right clicking the name of the song
    actionChain.context_click(gotosong).perform()
    wdwfind("//nav/div[4]").click() #Selecting the add to playlist option
    wdwfind("//div[@class='mo-coverArt-hoverContainer']").click() #clicking on the playlist to add the song to
    sleep(2) 
    clear=wdwclick("//input[@class='_2f8ed265fb69fb70c0c9afef329ae0b6-scss']").send_keys(Keys.SHIFT,Keys.ARROW_UP) #clearing the search box
    driver.refresh()
    sleep(1)

我已调查您的问题背后的原因。如果您尝试在播放列表中添加歌曲，请找到解决方案。由于 DOM 中的动态元素，您面临上述问题。同样在运行以下代码后，我得到了会员窗口，因此无法继续。
