如何在Instagram-API中将传送带媒体与图像或视频媒体区分开来？

from InstagramAPI import InstagramAPI

# 创建InstagramAPI对象并登录
api = InstagramAPI("your_username", "your_password")
api.login()

# 获取用户的最新帖子
api.timelineFeed()

# 遍历帖子列表
for post in api.LastJson['items']:
    # 检查媒体类型
    if post['media_type'] == 1:
        # 处理图像媒体
        image_url = post['image_versions2']['candidates'][0]['url']
        # 其他操作...
    elif post['media_type'] == 2:
        # 处理视频媒体
        video_url = post['video_versions'][0]['url']
        # 其他操作...
    elif post['media_type'] == 8:
        # 处理传送带媒体
        carousel_media = post['carousel_media']
        for media in carousel_media:
            if media['media_type'] == 1:
                # 处理图像媒体
                image_url = media['image_versions2']['candidates'][0]['url']
                # 其他操作...
            elif media['media_type'] == 2:
                # 处理视频媒体
                video_url = media['video_versions'][0]['url']
                # 其他操作...
