我正在尝试抓取以下网站:https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador
我要做什么:
通过移动滑块来模拟数量和持续时间。我正在尝试使用网络驱动程序找到它们。
但是我不能,事实上我已经开始抓取了。
出现的错误如下:
/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:12: DeprecationWarning: use options instead of chrome_options

由于类名中的空格,您的xpath无法正常工作。不知道这是不是唯一的问题,但是是一个问题。如果该类名正确,则以下行应找到您的元素。
webdriver.find_element_by_css_selector('div.res.r1')

您可以尝试以下操作来输入值
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys
url = 'https://simuladores.bancosantander.es/SantanderES/loansimulatorweb.aspx?por=webpublica&prv=publico&m=100&cta=1&ls=0#/t0'
driver = webdriver.Chrome()
driver.get(url)
amount = WebDriverWait(driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "#amount")))
amount.clear()
amount.send_keys(6000)
WebDriverWait(driver, 30).until(lambda driver: driver.execute_script('return jQuery.active') == 0)
term = WebDriverWait(driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "#term")))
term.clear()
term.send_keys('60 meses')
term.send_keys(Keys.TAB)
currentCuota = driver.find_element_by_css_selector('.r1 span').text
WebDriverWait(driver, 10).until(lambda driver: driver.execute_script('return jQuery.active') == 0)
while driver.find_element_by_css_selector('.r1 span').text == currentCuota:
continue
print('Tu cuota mensual: ' + driver.find_element_by_css_selector('.r1 span').text)
