弃用警告：find_elements_by_* 命令已弃用。请使用 find_elements() 而不是在 Google Colab 中使用 Selenium

Question

有一些函数可以与 selenium 一起使用，这些函数有一定的输出，但是当我在 google colab 中打开它们时，我得到了一些我不想要的输出，这降低了理解力.

有没有办法不获取示例中'BETSWITHBOT'和'HATAYSPOR'之间的输出？

我的代码：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.support.ui import WebDriverWait
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')

chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)

Specify that the "find_element_by_* ..." warning is a deprecation warning (#9700)

解决方案

而不是 find_element_by_* 你必须使用 find_element()。例如：

You need to add the following import:
from selenium.webdriver.common.by import By

而不是使用：

takimlar = driver.find_elements_by_xpath("//table[@id='predictions_table']/tbody/tr/td[3]")

您需要使用：

takimlar = driver.find_elements(By.XPATH, "//table[@id='predictions_table']/tbody/tr/td[3]")
