此函数def get_heart_icon_X path（post_num）错误 pl z帮助运行代码

我正在尝试为Instagram编写自己的bot python selenium bot，以进行一些实验。我成功登录并喜欢在搜索栏中的首页供稿页面上，将我带到以下网页：网页

但是我不知道如何喜欢提要中的照片，我尝试使用XPath和以下路径进行搜索：“ // [@ id =” reactroot“] / section / main / article / div1 / div / div / div / div1 / div1 / a / div”但这没有用，有人有想法吗？

        driver = self.driver
        driver.get("https://www.instagram.com/")
        time.sleep(2)
        login_button = driver.find_element_by_xpath("""//*[@id="react-root"]/section/main/article/div[2]/div[2]/p/a""")
        login_button.click()
        time.sleep(2)
