如何实现Python selenium键盘鼠标事件

#cording=gbk
import os
import time
from selenium import webdriver
from selenium.webdriver.common.by import By #导入by方法
from selenium.webdriver.common.action_chains import ActionChains  ##对鼠标事件操作
from selenium.webdriver.common.keys import Keys # 对键盘事件操作

current_path=os.path.dirname(__file__)
firefox_path=current_path+"/../webdriver/geckodriver.exe"
driver=webdriver.Firefox(executable_path=firefox_path)
driver.get("http://www.baidu.com")

# 先输入百度
driver.find_element_by_id('kw').send_keys('百度')
time.sleep(3)
# 1.删除度
driver.find_element_by_id('kw').send_keys(Keys.BACK_SPACE)
time.sleep(3)

#2.清空输入框，重新输入值
driver.find_element_by_id('kw').clear()
driver.find_element_by_id('kw').send_keys('安琪儿')
time.sleep(5)

# 3.ctrl+a 全选输入框里的内容
driver.find_element_by_id('kw').send_keys(Keys.CONTROL, 'a')
time.sleep(3)

# 4.ctrl+x 剪切输入框里的内容
driver.find_element_by_id('kw').send_keys(Keys.CONTROL, 'x')
time.sleep(3)

# 5. ctrl+v 粘贴剪切的内容
driver.find_element_by_id('kw').send_keys(Keys.CONTROL, 'v')
time.sleep(3)

# 6. 回车
driver.find_element_by_id('su').send_keys(Keys.ENTER)
time.sleep(3)
