Summary: Python bindings for Selenium什么是“鼠标悬停”
当鼠标光标移到页面某元素上并停留，页面以文字、图片等形式弹出内容，当鼠标移开时，弹出内容消失。如百度首页以下样式：
通过”move_to_element”方法实现

ActionChains(driver=driver).move_to_element(more_menu).perform()
time.sleep(3) # 仅为能达到悬停效果睡眠，可删除
driver.quit()通过调用JS方法实现

more_menu = WebDriverWait(driver=driver, timeout=15).until(EC.visibility_of_element_located((By.XPATH, menu_xpath)))
driver.execute_script(js, more_menu)
time.sleep(3)
driver.quit()通过调用”move_by_offset”方法实现
此方法不常用，因为获取偏移量较为困难.

driver.maximize_window()
ActionChains(driver=driver).move_by_offset(xoffset=1, yoffset=1).perform() # 相对当前位置的X/Y偏移量
time.sleep(3)
driver.quit()通过调用”move_to_element_with_offset”方法实现
此方法不常用，因为获取偏移量较为困难.
