python web Selenium 中find_element用法

Question

from selenium import webdriver

driver = webdriver.Edge()

driver.get(r'https://www.baidu.com/')

driver.find_element(id, 'kw').send_keys("123")
这句代码为什么向搜索框传递123是报错?

selenium 什么版本？

3.141 是这么用的

driver.find_element_by_id('kw').send_keys("123")

高版本要这样

from selenium import webdriver 
from selenium.webdriver.common.by import By
 
#打开浏览器
driver=webdriver.Chrome()
#打开百度
driver.get('http://www.baidu.com')
#输入框 输入selenium
driver.find_element(By.ID,'kw').send_keys('selenium')
