    search.send_keys(Keys.CONTROL,‘c')

    search.send_keys(Keys.CONTROL,‘v')

5.鼠標(biāo)操作

    右擊

    element = driver.find_element_by_id(‘kw')

    ActionChains(driver).context_click(element).perform()

    element.send_keys(‘李煥英')

    單擊（左擊）

    btn = driver.find_element_by_id(‘su')

    ActionChains(driver).click(btn).perform()
