python3之selenium.webdriver 库练习自动化谷歌浏览器打开百度自动百度关键字

import os,time,threading
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver  = webdriver.Chrome()

driver.get('http://www.baidu.com')
print(driver.title)
assert "百度" in driver.title # 这是断言，如果有百度关键字就往下执行
selenium = driver.find_element_by_id("kw")#找到百度输入框的id选择器的元素名字
selenium.send_keys("python")#设置要百度的关键字如“python”
selenium.send_keys(Keys.RETURN) #发送请求
print(driver.page_source)#输出请求结果

#以下的是练习，自动忽略就好
