from selenium import webdriver
dr = webdriver.Firefox()
dr.get("http://www.baidu.com")


try:
    dr.find_element_by_id(‘kw111‘).send_keys("异常处理finally") #故意写错id，定位不到元素
    dr.find_element_by_id(‘su‘).click()
except Exception as e:
    print(e)
finally:
    print("finally")   #不论有无异常都会执行

try:
    dr.find_element_by_id(‘kw111‘).send_keys("异常处理else")
    dr.find_element_by_id(‘su‘).click()
except Exception as e:
    print(e)
else:
    print(‘else‘)  #无异常执行后续操作,有异常不执行

dr.quit()
