我想在视图中导入Trends.py文件：
我正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

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'
我现在该怎么办？
答案 0 :(得分：1)
需要完成两件事。
您需要在____init___.py文件twitter文件夹中进行from .trends import main
然后您可以导入view.py文件from .twitter import main

尝试将from pironews.feed.twitter.trends import main更改为from twitter.trends import main。
