Selenium find_element_by_css_selector定位输入框报selenium.common.exceptions.NoSuchElementException的解决方法

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：

C:UsersEDZDesktopselenium_demovenvScriptspython.exe C:/Users/EDZ/Desktop/selenium_demo/webdriver/Keys_Option.py
Traceback (most recent call last):

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:UsersEDZDesktopselenium_demovenvScriptspython.exe C:/Users/EDZ/Desktop/selenium_demo/webdriver/Keys_Option.py

Process finished with exit code 0
