通过class 属性定位元素 (class 可能不止一个)

el3 = driver.find_element(By.CLASS_NAME, 's_ipt')

from selenium.webdriver.chrome.service import Service
from selenium import webdriver
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome(service=Service('/usr/local/bin/chromedriver'))
driver.get('https://baidu.com')
#定位元素
# el1 = driver.find_element(By.ID, 'kw')
# el2 = driver.find_element(By.NAME, 'wd')
el3 = driver.find_element(By.CLASS_NAME, 's_ipt')
print(el3)
# print(el2)
time.sleep(100)
