我想在我的视图中导入 Trends.py 文件：

我在视图文件中执行以下操作

from pironews.feed.twitter.trends import main

def twitter_trend(request):
    output = main()
    print(output)
    return HttpResponse(output, content_type='text/plain')

这是我的trends.py文件

    for i in json_obj:
        for j in i['trends']:
            print(j['name'])

但是当我运行服务器时出现以下错误

PiroProject/pironews/feed/views.py", line 20, in <module>
    from pironews.feed.twitter.trends import main
ModuleNotFoundError: No module named 'pironews.feed'

我现在应该怎么办？
