早晨操作find_element_by_css_selector定位输入框的代码如下：
#打开搜狗搜索页面
driver.get('https://www.sogou.com/')
driver.find_element_by_css_selector('#sec-input').send_keys(Keys.CONTROL,'v')
sleep(2)
driver.quit()
执行时报：

搜狗输入的源码如下：
经检查是find_element_by_css_selector后面定位输入框class的格式有误
正确代码如下：
#打开搜狗搜索页面
driver.get('https://www.sogou.com/')
driver.find_element_by_css_selector('.sec-input').send_keys(Keys.CONTROL,'v')
sleep(2)
执行操作正常没有报错
C:\Users\EDZ\Desktop\selenium_demo\venv\Scripts\python.exe C:/Users/EDZ/Desktop/selenium_demo/webdriver/Keys_Option.py
Process finished with exit code 0
