我使用 Python Selenium 來獲取 Youtube Video URL。我首先加載主頁，然后單擊隨機結果。從第二頁開始，我想在右側獲得建議的視頻。但是當我這樣做時，驅動程式只是將建議的視頻添加到主頁上的視頻串列中。我不知道為什么...所以我需要重置或清除 find_elements 之間的某些內容
driver.get('https://www.youtube.com/')
time.sleep(8)
items = driver.find_elements(By.XPATH, "//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]")
for i in items:
url = i.get_attribute("href")
print(str(url))
rand = random.choice(items)
rand.click()
time.sleep(10)
# GET SUGGESTED VIDEO ON THE RIGHT
yt_right_pane_items = driver.find_elements(By.XPATH, "//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]")
for i in yt_right_pane_items:
url = i.get_attribute("href")
print(str(url))
主頁的輸出：

第二個輸出 = 第一個 find_elements 的視頻 第二個 find_elements 的視頻

在第二個 find_elements 上，我只想從被點擊的頁面中獲取新視頻。
uj5u.com熱心網友回復：
問題不是Selenium也不是- 它保留了這些鏈接但隱藏了list。YouTube
您xpath搜索所有鏈接 - 甚至隱藏 - 但它應該只搜索可見部分
//div[@id='columns']
完整的 xpath
//div[@id='columns']//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]
如果你只想要SUGGESTED VIDEO ON THE RIGHT然后搜索
//div[@id='related']
完整的 xpath
//div[@id='related']//a[@id='thumbnail'][@class='yt-simple-endpoint inline-block style-scope ytd-thumbnail'][contains(@href, 'watch?v=')]
其他方法是使用set()洗掉重復元素
new = list( set(second_list) - set(first_list) )
duplicated = list( set(second_list) & set(first_list) )
它可能很有用，因為您可以在所有頁面的建議中重復。
