Question

我正在从网页中获取债务对股权比率的值。

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
options = Options()
options.add_argument('--ignore-certificate-errors')
options.page_load_strategy = 'eager'    
driver = webdriver.Chrome(ChromeDriverManager().install(),options=options)
wait = WebDriverWait(driver, 20)
driver.get("https://www.moneycontrol.com")

inputElement=wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#form_topsearch>.txtsrchbox.FL'))) 
inputElement.send_keys('3IINFOTECH',Keys.ENTER)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#proceed-button'))).click()

driver.implicitly_wait(30)
print("---")
try:
    driver.find_element_by_link_text("Financials").click()
    driver.find_element_by_link_text("Ratios").click()
    driver.find_element_by_link_text("Leverage Ratios").click()
    elem = driver.find_element_by_xpath("//*[@id='body']/table//thead/tbody/tr[1]/td[2]")
    print(elem.text)
except e:
    print(e)
