I want to import the trends.py file in my views:

I am doing the following in the views file

from pironews.feed.twitter.trends import main

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

This is my trends.py file

    json_obj = json.loads(tweet['tweet'])

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

But when I run the server I am getting following error

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

What should I do now?

Answer 1

There are two things which needs to be done.

• You need to do from .trends import main in the ____init___.py file twitter folder

• You can then import in the view.py file from .twitter import main

Answer 2

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