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

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,我会得到一些我不想要的输出,这会降低理解。

有没有办法在示例中不获取“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('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)

def betswitsbot():
    print("BETSWITSBOTn")
    driver.get("https://www.betswithbots.com/")
    takimlar = driver.find_elements_by_xpath("//table[@id='predictions_table']/tbody/tr/td[3]")
    evTahmin = driver.find_elements_by_xpath("//table[@id='predictions_table']/tbody/tr/td[4]")

    altTahmin = driver.find_elements_by_xpath("//table[@id='predictions_table']/tbody/tr/td[7]")
    ustTahmin = driver.find_elements_by_xpath("//table[@id='predictions_table']/tbody/tr/td[8]")

    for x in range(0,len(takimlar)):

            #print(ev, evTahmin[x].text, xTahmin[x].text, depTahmin[x].text, dep, altTahmin[x].text, ustTahmin[x].text, ngTahmin[x].text, gTahmin[x].text, sep="t")

            elif float(depTahmin[x].text) > 50:

指定“find_elementby* ...”警告是弃用警告 (#9700)


解决方案

您必须使用 find_element() 而不是 find_element_by_* 。举个例子:

您需要添加以下导入:

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]")
    
  • 你需要使用:

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